Porsche 997 Buyers Guide

Updated on March 22, 2016

What to Consider When Buying a Porsche

Start with these questions:
• What year you want?
• Manual or automatic?
• Which Porsche model?
• Which options are essential?

The Porsche 997 started arriving at the end of 2004 and was met by pretty much universal applause. It's updated looks harkened back to the much-loved 993, but with a modern twist. Performance and handling were also better, with many reviewers claiming Porsche had finally managed to eliminate the undesirable effects of having the engine slung at the back of the car (something all auto journalists seem to state every time a new 911 arrives).

In terms of competitors, the 997 slayed nearly every car, until the arrival of the Audi R8 three years later. I personally saw the R8 as a closer challenger to the GT3 or V8 Ferraris and V10 Lamborghini's due to the lack of rear seats, than to the Carrera 2's and 4's it was pitted against.

In terms of purchasing decisions, there are two main choices you need to make.

  1. Which flavor of 997 do you want? Porsche released the car in a dizzying array of types, with varying different amounts of horsepower and drive types.
  2. What year Porsche do you want? The 997 received a facelift for the 2009 model, which improved the cabins electronics, increased engine power, and added direct fuel injection to improve economy.

A factor that is obviously going to affect all these decisions is budget.

Which Year Should You Choose?

Although I discussed year as the second point that should be consider, I want to focus on year first.

The 997 received a major facelift for the 2009 model year. In forums, you will generally see these cars described as 997.2, and cars for the model years 2005 - 2008 as the 997.1. However, there were some engine changes between 2005 - 2008 that helped improve, but not totally eliminate, a design weakness that was fully rectified in the 997.2 model.

If you have done any research on the 997, you will have come across something known as IMS and RMS. You may have even heard reference to the term "scored bores" (a parts failure that can cause the engine to rip itself apart). I am not an expert in any of these areas, and so will not go into great depth, but my understanding is that this risk is important when looking to buy a 997.

It's worth noting that the problem is relatively uncommon. There are also steps you can take to mitigate the issue. A preventative step is to install third-party parts that eliminate the problem. You can also purchase a warranty.

I also want to point out that some models of 997 are less susceptible, if not immune, to all or any of these issues, either due to model type or year. I know that the tales on Porsche forums make for some pretty worrying reading in regard to these issues. They scared me when I first read about them.

Early 2005 cars had a smaller IMS bearing installed. These were changed, but you will need to do some research to be more precise. Dates on the various forums seem to alter, so don't always take everything they say to be gospel. The earlier cars fitted with the smaller IMS, the more susceptible to major failure than the revised bearing. But revised bearings are not a cure, so don't assume that a car equipped with this upgraded IMS bearing means there is no risk.

You should stay away from early 997, i.e. those delivered in late 2004 to some time in 2005 (do your own research to be 100% sure). The price of the early 997 reflects the potential issues, but if you find a car with a good service history and get your ppi done, you are in a good place. Early cars with the smaller bearing can in fact have an advantage over later revised bearing 997.1's, as the fix to these LMS issues is far cheaper as less labour is required. Check out a company called LN Engineering for really detailed information about what is involved in swapping it out.

Note: If you want to know whether the car you are looking at is installed with the larger or smaller IMS bearing, get hold of the VIN number. It is possible to check this information. Again, visit Porsche owner forums.

Which Model Should You Choose?

Which 997 you choose will come down to personal taste. I have listed the model types below with a brief synopsis of each.

There are many choices in the 911 line. I honestly don't think there is a bad choice among them. Personally, I went for a 997.1 C2S cabriolet, because for me this car was going to be a toy for the weekends and not something I was planning on driving everyday. I chose a rear wheel drive 911 because this was my first one and I wanted to experience the full sensation of having the engine in the back of the car.

The reason my car is a gen 1 and not a gen 2 was purely budgetary. The 2009 models similarly equipped with similar miles were in the region of 14 to 16k more than I was willing to pay. I would have accepted a 997.2 Carrera convertible, however even these were still another 4 or 5k more. I didn't find one while I was looking that was more appealing than the car I eventually chose.


Often referred to as the base model, if such a term can be leveled at a 911, 997.1 models generated 325 hp with the facelift, a number that rose to 345 hp. The disadvantage that this model has, compared to the S version, is that there is a slight stigma to having what people term as the "base" model. This stigma has, however pushed prices down on this model, making these cars particularly appealing for those on a lower budget. Likewise, the facelifted Carrera offers a very good alternative to those who were certain they needed an S.

The 997.2 Carrera has only fractionally less horsepower than the 997.1 Carrera S, and has the advantage of a better cabin (namely the nav system, or PCM as it is referred to by Porsche) and is also meant to be immune to the IMS issue, better economy, improved breaks of the 997.1 Carrera, and updated exterior looks. Many argue that the 3.6 litre engine of this car is also the better sounding.

  • Carrera S - 355 hp in 997.1 form and 385 in 997.2. In 997.1 form the S had improved breaks and suspension as standard over the standard Carrera. 997.2 S has the advantages of better cabin, exterior refresh, performance, and economy improvements over its gen 1 counterpart.
  • Carrera 4 and 4S The main difference is the drive train as the car moves from a rear wheel drive car to an all wheel drive one. The other advantage, or desirable feature depending on your point of view, is that the all-wheel-drive version has a fatter rear end than the two wheel drive counterparts. Cosmetically many, including myself, find this a very appealing feature. The four-wheel-drive model was also ever so slightly faster around the track than the two-wheel-drive model (fractions of a second), but is interesting nonetheless, as this was the first time an all-wheel-drive variant of the 911 was quicker than its rear-wheel-drive counterpart. Which you prefer to drive is going to come down to personal preference. 997.2 saw the reintroduction of the red reflective strip to the back of the car which helped to further distinguish it from the rear wheel drive model.


All of the models listed below have the option of coming as a convertible. These models tend to command a slightly higher price than the equivalent coupe version of the same model. Disadvantages would be loss of the classic coupe lines, also slightly less rigid structure than a coupe, although you would have to be a far better driver than me to feel the limits. The main advantage is the ability to drop the top on a sunny day and enjoy the noise of the flat six as it pulls you closer to the redline.


Allows the feel of a Cabriolet while maintaining a solid roof and structure. A full-glass roof gives an airy feel to the cabin, but does add weight to the structure and necessitates a slightly softer suspension setup.


If you want to get around even more quickly, while maintaining all the creature comforts then this is the option you will find most appealing. An AWD system gives this car huge levels of power and torque. Gen 1 cars were based on the 3.6 Metzger engine and delivered 480 hp. Gen 2 cars had a more powerful 500 hp engine. The Metzger engine in the Gen 1 car is seen as a classic developed from years of motorsport knowledge, with great potential for upgrades and devoid of the problems that graced most other 997 gen 1 cars. This may allow the car to guard its residual value better going forward. The engine in the Gen II is based off new construction. It is still probably too soon to say how good a unit it will be. Turbos were also made available in cabriolet form. An S version with even more horsepower arrived later on in the gen IIs life.


  • GT3 and GT3 RS Without fail, these cars have dominated the drivers' best award category since they arrived on the market. In essence, they represent the nearest to a race car level of Porsche allowed on the open roads. All naturally aspirated, they offered 415 hp in Gen 1 and 450 in Gen 2 format. You will often hear the term "club sport" when talking about GT3's. This tended to denote the fitment of the roll cage to the GT3 as well as bucket seats, which offer a slightly more track-focused version of the car. RS versions of the models stripped out even further weight and made use of the wider Carrera 4 body shell while remaining rear-wheel drive and included more aggressive aero packages. Truly inspiring machines.
  • GT3 4.0 I have chosen to separate this car out from the other GT3's as it was an extremely limited production car. I personally believe this car will enter the hall of all-time great 911's, along with the 2.7 RS. Still very new, it's too hard to say what will happen in terms of depreciation, but long-term you would have to bet on this being one of the few that may actually start gaining in value. With a 500 hp naturally aspirated engine and a more extensive aero package than we had seen on other 911 GT3's, its old-school charm made it hit among road testers.


The GTS arrived later on in the life of the 997. It is the most powerful naturally aspirated 911 you can purchase that still maintains the rear seats. With 410 hp, this car delivered exactly the same performance as the limited edition speedster and sport edition 911s, which were released earlier.. The GTS had a number of additional little tweaks, such as black tailpipes and wheels which were also attached with a single central bolt. This car was incredibly well-received and for many offered the ideal balance between cost, performance, and flexibility. AWD and RWD versions of the car were available, as well as coupe or cabriolet configurations.

GT2 and GT2 RS

Again, a more track focused version of the 911, however this time with turbo-charged engines unlike the turbo-only RWD. The GT2 997 was the first Porsche-produced 911 with a speed in excess of 200 mph. The RS version offered a lightweight and a slightly more striking appearance, due the large amounts of carbon fiber visible on the bodywork (such as the front bonnet). The RS version was extremely rare, with a very limited production run.

Speedster and Sports Edition

Both of these cars were limited-edition, with bespoke body work and potent 410 hp units. In both cases these cars are more appealing in-person than in the magazines. The twin bumps in the roof and ducktail of the sports edition gave this car a very aggressive look on the road. I can see in both cases why these cars are highly desirable, however their bigger price tag put them beyond reach for most of us. The GTS offers nearly the same experience without the bespoke bodywork, however due to their exclusivity I am sure these special edition cars will hold there value very well.

Manual or Automatic

The manual gear box on the 997 Gen 1 and Gen 2 is a great unit. If I had to make one criticism, I would level it at the position of reverse and first gear. Reverse gear is selected by pushing hard to the left and then up. First gear is selected by pushing to the left and then up. The first time I drove a 997 Carrera I got caught at a tricky junction with very fast changing lights on a hill. I managed to select reverse rather than first gear and almost had a very embarrassing situation. I haven't had this issue with my latest car.

If you prefer the two-pedal option, there are a couple of things to know. The first is that 997 Gen 1 cars have an automatic box that is referred to as a Tiptronic unit. These cars tend to be slightly slower accelerating than the manual. By today's standards, this gear box is very dated, however having never driven one I can't coment on whether they are still nice to drive or not. With the arrival of the Gen II 997 Porsche introduced PDK. A twin clutch gear box, as seen first in the Audi and later VW, this box offered smoother changes and great acceleration times. I haven't driven a Porsche equipped with this gear box but a friend who has said it was very good. I must admit I have always been impressed with it in the Audi A3 I had previously and in the current Golf GTI my wife has today.

Personally I wanted a manual as I wanted to feel more connected to the car. Also, the 991 manual gear box has received less stellar reviews and part of me feels that if I am ever lucky enough to have another 991, I would probably lean toward the PDK box. The 997, in my opinion, will mark the end of the manual box being the gear shift of choice in the 911.

  • PDK buttons versus paddles One of the main criticisms of PDK when it arrived was the control mechanism Porsche implemented. This actually led to them to release a sports design steering wheel with paddles, bringing the control method into line with other car manufacturers. What you prefer is going to be a matter of personal choice. Note, however, that if the car you find is equipped with the buttons and you prefer paddles, this shouldn't be a dealer breaker. You could purchase the Porsche sports wheel with paddles, or buy one with buttons and pay a third-party to upgrade it with paddles. This is probably a cheaper option.

Which Options Are Essential?

After you have decided on your year and model type, the next thing to consider is which options you want. Again this is going to be largely subjective. Here is a brief overview of my opinions.

  • PASM (Porsche Active Stability Management) This was actually standard on Carrera S but not on the Carrera. It allows the car to be used in a more everyday mode or switched on for sportier (read harder) setting as well.
  • Seat Types Sports, standard, power, adaptive sports, and bucket. Which are the best? Well this is really going to depend on what you want. Even the standard seats give lots of support. Power and adaptive sports seats are great if more than one person drives the car, as the memory option moves the seat to your preset position as soon as you use your personal key to open the car.Bucket seats while expensive add to a more hard core racing feel while reducing weight. I have the 12 way power seats in my car which both my wife and I use and I have to be honest the memory function and the ease with which it works means I would be very reluctant to have non memory seats again. Having said that if I had a GT3 I would want the bucket seats....

PCM - This is control unit for the radio sat nav, memory settings in car etc. Definitely improved with 997.2 cars due to larger touch screen with Bluetooth and smartphone support. Note after markets kits can be added to 997.1 PCM kits to give Bluetooth and smart phone support.

Sports chrono Package - This option adds the strange dash mounted stopwatch and sports button to the console. When pressed sharpens throttle response. For PDK cars and turbos this is a very desirable option. In turbos it allowed an over boost option when pressed giving the car more torque. It also improves acceleration and gives launch control to PDK cars. Less necessary in others. Can include ability to track lap times etc as well.

Porsche Sports Exhaust (PSE) - A great option that when pressed gives a more aggressive and louder sound to the exhaust. Search on You tube to hear the sound improvement.

Porsche Ceramic brakes - Hugley expensive options so quite rare. Gives better stopping ability especially when used in a track type conditions. They are more expensive to replace and there was some issues with them if not allowed to cool properly. I personally wouldn't pay more for a car equipped with them on. They are lighter than steel breaks so do offer some great advantages. If you find a car with them on do a little bit more research to see if it is something you can live with. They come with Yellow calipers so do have a slight cosmetic effect on the way car looks as well.

Short Shifter - People say they are good not used one myself so can't add much value here.

Heated Seats - If you are getting a cab probably an essential option as it allows you to put the top down on those less warm sunny days. Nice to have if you use the car as a daily driver for those colder mornings.

Bose Sound - Improved sound system. Sounds pretty good to me not heard the base system to compare it to however. Listen to both if you can to decide if it is essential or not. The best system you can get that is standard from Porsche.

X51 - This is actually a power pack you could purchase from Porsche that unleashed extra horsepower and torque. It was a seriously expensive option but could easily be retrofitted by Porsche if you decided at a later date this was something you desired. This involved installing new airfilters, radiator and parts to the car but performance in the 997.1 Carrera S went from 355 to 381 and the gen 2 car went from 385 to 408. Interesting to note that this can still be picked up from Suncoast parts for a cool 12500 USD.

Wheels - In my personal opinion wheels are one area on the car that you can change quickly that makes a radical difference to the overall way a car looks. Carrera Base models came fitted with 18 inch standard wheels and all other models with 19 inch wheels. Don't be put off if the car you find doesn't have your ideal wheels. As you can see to the right OEM and third party wheels can be picked up easily on ebay or from other specialist and even the classified sections of forums. Don't forget you have the option of selling your own wheels onso changing the wheels doesn't necessarily have to be a very expensive exercise.

Cosmetic Changes - There are too many to list you can literally customize the whole interior with different pieces. Additional leather, carbon, wood, aluminum etc. You can get some really cool changes such as different color seatbelts or seat stitching that help to make the cabin feel that bit more special.

What to do when you find the car?

If you are anything like me pretty much the first car you look at will be the right car. I wish I could coach you on how not to be emotional when you view one of these cars but alas as soon as I saw one sat in it and heard the engine roar I wanted it.

Luckily I had some help. Forums are a great place to go and post information up about the car you found. They give good feedback about the condition of the car, price, options etc.

The check list they fed back to me was as follows:

(Just as an aside and to give proper credit where it is due I am particularly grateful to Matty from 6speedonline for the majority of the following points)

1. Check that the tires all match (brand as well as N number) & tread left.
2. That the car hard starts when warm (TSB on alternator cable and perhaps needs changed?)
3. oil consumption? (these cars can burn oil, but it's good to know what you're getting)
4. sooty left exhaust pipe? (normal, but could also mean AOS is going or scored cylinder in right bank)
5. paint meter, signs of accidents
6. DME scan, also check for error codes. I have talked to a few people about what you want to see here. The rule I give you is basically any revs in the 1-3 range are ok if there is anything in the 4 or 5 walk away.
7. Shifts smoothly
8. service history
9. coolant cap has the newest rev, old ones leaked
10. battery in service date (these cars kill batteries, generally last 3-5 years)
11. spoiler squeak? (pretty normal, little silicone can fix)
12. check the alignment on a test drive, make sure wheel is straight and it doesn't pull
13. bolster wear on driver seat as well as scuffs on door jam (tell how careful previous owner was getting in and out)
14. hood or bumper too clean? These cars are rock chip magnets, depending a bit on mileage a super clean bumper could mean a respray which could mean a fender bender.
15. smooth idle
16. squeaks and rattles? (it's a sports car and a cab too, so it's bound to have them. Drive with the windows up and listen for them. Use it as a negotiating tool if you can)
17. ac buttons peel
18. curb rash

Ultimately you get a Pre Purchase Inspection (PPI). This helps to eliminate some of the unexpected surprises that arise. It is also a way of allowing you to get access to cars that physically are difficult for you to see. Various companies offer pre purchase inspections this can be with the local Porsche dealer or with third party companies such as carchex.

Why detailers? These guys are the magicians of the car world they can take a car that you would honestly believe is a complete duffer and turn into concourse material.

If you find a car that mechanically checks out at a good price but you feel has not aged well in terms interior and exterior appearance it might not be as bad as you think. If you spend a bit of time on detailers forums you will see these guys working on projects for clients who have found mechanically sound cars that need a bit of tender love and care. By the time they have finished the car is honestly in better than new condition.

Arming yourself with the knowledge of what is possible and how much it would cost to rectify is a great tool in helping you find your ideal car. Look in the links section at the bottom of this article for access to a couple of detailers forums I frequent.

Warranty Yes or No?

For me the answer is Yes but that's because I am not a huge risk taker. I had also personally see the IMS issue occur 4 times. The first time was at the beginning of 2005 my boss at the time had just had delivery of his brand new 997 Carrera S tiptronic. A couple of weeks later I was pulling off the round about and there on the side of the road was his car. As I found out later the IMS bearing had gone and shredded his engine. The second time I saw this issue was in a base Carrera a few years later that did the same. The third time was much more recently a colleague had managed to purchase a car that was almost identical to the one I own today. He gave me a lift in and I remember being incredibly jealous. Just two weeks into his ownership the car lost power and chucked a bunch of oil out of the bottom. He had suffered the IMS issue but unlike the first two cases which were covered by Porsche warranties he had none. His Porsche dream was crushed he had a car which didn't work a bill for almost 30k USD to replace it. Needless to say he ended up in litigation with Porsche and the previous owner but as far as I am aware he was never made whole. The fourth time was my boss again the same guy who had already suffered one engine failure and had to have his engine replaced. Again he was out of warranty coverage but because he had always had his car serviced with Porsche and was extremely good customer he had only to cover 10% of the cost.

The car I was purchasing while from a dealer was not from a Porsche dealer. This meant it came with no warranty. Because of the above issues I had described I was very conscious of the fact I was not financially in a position where I could afford to eat 20k plus of costs for a new engine if the problem occurred. I therefore chose to purchase a third party warranty.

The dealer I was purchasing the car from offered this service. However rather than just accepting this I shopped around. In the end I went with a company called Carchex who were able to offer a full bumper to bumper warranty for three years for 2/3 rds of the price offered by the dealer.

Under what circumstances would I deem not having a warranty to be less of a risk. If the car you are purchasing is a gen 2 then the IMS risk is gone. This means one of the main things that could destroy your engine is gone. 997 Turbo's and GT3 were also built with engines that were not known to suffer from this issue so are less of a risk. If the car you are purchasing also has the IMS bearing replaced already by LNE unit then you should be safer. Warranty prices are dependent on number of miles you have and the age of the car. In three years time when my warranty expires my car will be 9 years old. At this time I will have a decision to make. My choices are to either sell the car, buy a new warranty or pay to have the IMS replaced. As I will have known the car by that time well I suspect that renewing the warranty would be the least attractive option. If I keep it (hard to say at moment as I am in the honeymoon period and my response at moment would be I will never sell it) then having the IMS replaced is probably the more financially astute direction to take.


One of the most common questions I see in forums relates to depreciation. Any car buyer wants to know which factor determines how much their new purchase will depreciate: how many miles they have driven it or how many years they have owned it.

This really is an impossible question to answer, and probably the wrong one to be asking when you are looking at buying a car like this. However, for the sake of this article I thought I would go over it briefly.

The 997 has declined relatively quickly in value. This is in no small part helped by the fact that the previous model 996 has not been kindly looked upon. Also, early models have a potential fatal flaw in their engineering which, thanks to forum communities, has led people to be slightly wary of these cars. Will this continue?

This depends to a great degree on the success or lack of success on the 991. If the 991 steering and enjoyment factor prove to be diminished to the extent that the 997 is seen as a last of breed car, then 997s will appreciate in value. However, my personal opinion is that the 997 is probably not going to get the same value boosts that the 993 enjoyed, because the 991 is equally or more attractive than the 997.

One positive factor for 997, however, is that the 991 is more expensive. The 997 also has the claim of being the last hydraulically steered 911.

Ultimately I think values of 997s will decline further, but amongst the older cars there will start to be a more obvious split. Those cars that are maintained well will start to plateau while cars that are not so well looked after will continue to fall ever lower. I would always expect to see a split in the GEN I and GEN II prices, much the same way as you see in the 996 or 993 model revision years.

My advice to you would be to forget about the depreciation and enjoy the car for what it is—a great driving machine. If you maintain it well and look after it there will always be someone who wants to purchase this car off you. The question is, will you be willing to give it up?

      Dear people i went throught all the negative comments everyone does

      So here is my advice as a 3 porsche car owner who ended up buying a 2007 997. Buy the c2 the s the c4s and for 3 k do the vertex ims and cylinder upgrade and get your worries off your chess this will garantee not only peace of mind but that ur car wont have any problems mechanically. Good luck go out and buy the car you want enjoy it like i am and sell it later or keep it dor your collection!

      To Lynne @PorscheProblems.

      I'm going through EXACTLY what you went through. I'm so incredibly depressed about it and furious at the premier auto brand in the world not doing anything to help me. Actually makes me sick. I honestly have no answers. I went out on a limb to get this car I've always wanted (2007 cs4) and now I'm in a terrible position not knowing where to turn.

      Hi you made a comment you would purchase a warranty as you don't like a gamble,but beware most of the warranty companies out there including Wise all will happily sell you a warranty but it will not cover all the common fault issues wth your Porsche.IMS and bearing faults are not covered so you can pay up to £2000 for a warranty that will cover all things that don't go wrong but not the things that do ,so beware and ask what is covered!!

      Sorry to break it to you but if you're over 50 you have a better chance of getting cancer than an IMSB failure. Selling snake oil to 500k 996,997 and boxter owners is profitable and the updated part is not a permenant fix.

      Hope to own one of those cars one day or another. My question is: Buying from a Porsche dealer , is it a strategy that could help to solve some of the "lemon problems"? If i buy from an independent dealer, ill probably make the PPI in a Porsche dealer and he'll tell me what job have to be done, if its a good etc. But if the dealer IS selling me the car... Does the "honesty" will be the same?

      2005 997 owner (prefer the lighting design over the 997.2) metallic blue (similar to 991 Lapis blue) - its an S model - manual - just about to hit 34K miles - car is running great - confirmed with Porsche over the phone that my vin# is an affected IMS/RMS build as it is from the first production run in Q4 2004 - slapped a power train warranty on it just in case - change the oil more frequently than advised by Porsche (I am doing 6-7000K) and I don't drive it like a pansy, let the engine break 4000/5000 rpm keep the oil pressure at 5 (on the farthest right dial) and drive the damn car at least once a week. Love it, best purchase ever, not planning on getting rid of it - just planning to eventually add either a Panamera, Macan or 991 Targa to the Garage in the future - P-cars rule.

      I just wanted to say something in regards to the above post by Porsche problems. This hopefully came out from the article itself as well. You need to go into the purchase of this car particularly the earlier versions of the 997 with your eyes open. Do the research, make sure the car has been serviced well and that the pre purchase inspection took place. For peace of mind it may also be worth servicing at a Porsche dealer as they do feel more obligated to help you out if an issue occurs while they were maintaining it. This is also ultimately why I chose to purchase an aftermarket warranty. The price of 996 and 997 cars also reflect this risk with 993 and 964 cars now fetching better prices.

      I am still loving my car for those who are wondering. She hasn't missed a beat yet and seems to be getting better and better as I get to know her more.

      PorscheProblems 4 years ago

      Hello all Porsche owners.

      You can buy a nice new Porsche for tens of thousands of pounds. Take out the Porsche finance to pay it up, take Porsche insurance, pay them for GAP insurance, take a £1500 a year warranty for the first few years and also get them to service it for the first three years. They will smile and be very kind to you whilst doing this BUT you've bought a defective car (which they know about).

      Its fact that there is an inherent problem with the Porsche 996/997 models which is known as the dreaded 'bore scoring'. Those two words can instantly raise fear of any owner of these vehicles as it's a fatal flaw that is costing thousands of innocent Porsche victims worldwide, thousands of pounds, in most cases in excess of £10,000 for a new engine. I am one of those unfortunate Porsche victims and I am definitely not going to be the last. THESE CARS WERE NEVER RECALLED. Porsche effectively thought that they would put their head in the sand and hoping that the problem would go away. Funny how the sales people at Porsche don't tell you about the potential issues when you buy the car.

      WHY would Porsche think they had no need to address the problem?. The average car manufacturer takes their responsibly and RECALLS the car to rectify the problem. However when you buy a Porsche and pay £53500 for a two year old one you don't expect to be replacing the engine after 7 years of ownership. I had never heard of the dreaded 'scored bore' issue until my car started showing the highly obvious symptoms: excessive oil consumption, noisy engine and sooted left tail pipe, there are no shortage of stories on hundreds of forums from Porsche victims around the world.

      The customer services are very arrogant, cocky, disinterested and don't want anything to do with you. It's almost like they are non existent especially as your 'loyalty to the brand' (actual quote from Rachel at Porsche UK HQ) is somewhat lacking over the past 3 or 4 years as I failed to get my car serviced at the Porsche dealer and instead used a highly recognised Porsche (non dealer) garage for my servicing, nor did I continue with my £1500 a year Porsche warranty and my car is now over eight years (jan 2005) old so its basically a case of 'tough' you have not remained loyal enough to the brand for us to even consider any form of 'goodwill'.

      They have indeed told me that in order for them to asses what level of goodwill, if any, they will give me (and by my lack of loyalty to the brand over the past few years I suspect the goodwill would be non existent or an absolute insult) I will have to get my engine ripped out at the Porsche dealership for them to wiggle their way out of any liability...oops I meant ...asses the problem to conclude whether it is the dreaded 'scored bores' or not. In the process I will be left carless. Now, all I want to know from them is if they are of the opinion that it is 'scored bores' and based on my lack of loyalty to the brand (that is so laughable) they must be able to tell me now, before taking my car to pieces, what level of 'goodwill' I am likely to get, if any at all.

      I have heard so many stories of Porsche dealers asking Porsche victims to either pay up to get their car engine replaced or get the car towed off their premises so as I don't want to be caught between a rock and a hard place all I want to know is what, if anything am I likely to get? If their level of goodwill was going to be £500 towards the cost of a £15000 engine replacement then I would most definitely be towing my car out of there never to set foot in a Porsche garage again. They have put so many people in that position and I am not going to follow suit.

      Many people will say, 'well you can afford a Porsche so you can afford to pay for repairs' which is absolutely true but not the issue here, I have no problem paying for an expensive repair that is not a well documented problem with Porsche engineering and an inherent one that was going to happen regardless of who serviced my car over the years or how well I drove it or how often I serviced it etc. This was ALWAYS going to happen so for Porsche to try to wiggle out of paying for a new engine, not just for me but for other Porsche owners around the globe, is ridiculous and its daylight robbery.

      You buy a Porsche expecting it to last a very long time....you certainly don't expect it to end up in the ever expanding Porsche graveyard after just 7 years of ownership and 72k miles on the clock!

      Just to highlight Matty's feedback was only used in the checklist section of this article.

      Just wanted to publicly say thank you to Matty for the points list. The majority of that list came from him although a few points also came from other members of the 6speedonline and rennslists communities. He was definitely the biggest contributor and as such deserved to have been credited in the article. This has now been rectified. The link to 6 speed was available in the links section and as stated all this information came from forums and various magazines I have read and my own personal experience. Plagiarism is harsh as it would suggest I was looking to profit by passing off information as my own in order to profit in some fashion or other, good grade or money etc.

      HI Ed

      GT3 and Turbo engines in 996 and 997.1 have no IMS issues. 997.2 all types has no IMS issues either.

      Hi Peter

      Good luck with the purchase I am sure you will love the car. As to your question of the base vs the S. I am going to slightly shirk the responsibility by saying you should test drive both and see which one you prefer. I will however say that this is also budget dependent. A ropey not cared for S is a worse choice than well looked after base. You are also buying at the perfect time of year there is a local 997.1 C2s in grey at a Porsche dealer with 50k on the clock and all the options for 38k now that is a bargain.

      Thanks for a great write up. It has helped a great deal. Off for a 997.2 purchase in the next 2 weeks. Do I stick with the classic Carrera or plump for an "S"?

      Hi, I just bought a Carrera S 2009 997 (997.2) from a second hand dealer. But I've been checking around the engine to look for the VIN Number and still couldn't locate it. Anyone could help me locate for it? Thanks

      Great Summary. I purchased a 2008 997 was the IMS issue corrected by then, I believe so not certain. Does anything make the IMS more likely to break ie running car at high speed track etc or just random event

      No the Turbo .1 does not suffer from this issue. By all accounts the Metzger engine it uses is very robust.

      I have a 997 s gen 2.

      I took out the 991 and was considerably disappointed in the lack of driving feeling with the steering, porsche need to re think this one.

      The 997 stands out to be the ultmate porsche so far.

      Hopefully this will reflect on the value when I come to sell.
