Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hello everyone, I am new to the forum, but have been lurking for a bit and will soon be a P/Car owner. I have tried to digest all of the info related to the benefits and concerns of both models, but would like to hear opinions from actual owners. At the moment I am looking at a 2003 C4S and a 2001 Turbo. Both are in the color profile I want, 6 speed, and have similar options. -The C4S has 40,000 miles 3 owners and a good service history. Private sale. -The TT is a 50,000 mile 1 owner, dealer maintained trade in at the original dealership... Has every service on history and belonged to a longtime customer. The TT is about $9,000 more, and is almost perfect to my inspection. Is the tt less susceptible to some of the common 996 issues? And what is the carryover from the other turbo cars that makes the IMS less of a problem. Thanks in advance..

POST 2Original post

Can't go wrong with the TT. It doesn't have the IMS problem because it is a different engine block but this block has its own set of problems with coolant coupling leaks. If your more into having the turbo look without the ugly wing and don't care about the lack of power, the C4S is a pretty car to have. It really stands out in the crowd.

POST 3Original post

I'd probably go for the TT if the extra $$$ wasn't a big concern. Way more powerful with an engine block known for being one of the best Porsche has ever made. The turbo motor does not suffer the IMS issues of the M96 engine. They are however more expensive to maintain. That $9k extra could be more when factoring in maintenence. You could take the C4S and update components that will help to ensure many years/miles of happy motoring. A new clutch kit/RMS/IMS upgrade with flywheel could cost you close to $4k. If you go this route at least you kno that all of these parts are new and your good to go.

POST 4Original post

You can search the words "bullet proof" on the 996 Turbo forum as it relates to that engine. There are some very high mileage TT's out there (I think one over 200k on the 996TT forum). As mentioned above, the TT does have its own unique set of issues, although many on the market related to 2001s have already been updated. You need to drive both. If the ridiculous rush of the twin turbos that pin you back in the seat is significant to you, you may determine it is worth some type of premium. Maintenance costs may be another factor for you. Also, what is the price on the 01 TT? With 50k miles, I've seen these going in the mid-thirties, with some asking in the 40's. There's a bunch for sale on 6speedonline.

POST 5 / ORIGINAL POSTEROriginal post

Todd, They are asking 39k for the tt. I do plan on driving the car frequently. Not a daily driver, but certainly not a garage queen either.

POST 6Original post

Fair starting point, from the face of it. However, $30k for the C4S seems like a good deal. I don't follow the S's much, but I thought they were in the $35k-38k range. Assuming my math is right on the $30k.

POST 7Original post

Wow, asking $39k for a 1 owner, well maintained TT...that's the Porsche I'd pick hands down. Let us know what your choice is when you pull the trigger.

sorry for being a bonehead - but where is there Turbo forum? nevermind, found it

POST 10Original post

I've had both. Get a turbo but preferably not an 01 which has some special problems ( transmission in particular ) . More money to maintain but an amazing rush. There are good deals out there on both cars so be picky. If you get the C4S do the IMS bearing retrofit from Raby. Don't ask me how I know but it wasn't fun.

Oh yes. I forgot to mention the 2nd gear pop out on the TTs. I've seen many TTs for sale that say "no 2nd gear pop out issues" If you've made your way over to the 996TT forum by now, I'm sure you've found plenty of discussion on all of this and more.

POST 12 / ORIGINAL POSTEROriginal post

Sad news... went to the dealer today and the 01 tt was gone... booooooooo

POST 13Original post

Your decision is made,the C4S is your destiny

Not sure about that - lots of TTs on the market. I don't know officially, but they must have made more 996 TTs than C4S's, based anecdotally on the numbers I see for sale nowadays?? I guess if you compare an 03TT to an 03C4S, I would say a $12k difference now (TT higher). But if you compare to an 01TT, they seem to lose a lot of market value (first year 996TT). I'd say as much as $15k difference between 03 996TT and 01 996TT. Could it be that the C4S would be more of a collector's item in the future and depreciate at a slower rate than the TTs?

POST 16Original post

I really doubt 996 (turbo or normally aspirated) would be a collector car. There were just too many made.

big huge +1 GT3 maybe, and that's a big maybe.

POST 18Original post

996TT. USes the 993 Lower Engine Block...upgraded components and very solid. Even my repair shop says it is a great engine. Since you are looking at a 996 regardless...all the wear parts will be about the same (with exception of the rear spoiler). I have the TT as you can see and it is just awesome.

POST 19Original post

I opted to be part of the big butt club, but determined I couldn't afford the extra tickets with the turbo. Also, something about the smooth backside just seems more pleasing to the eye. Been happy ever since I made the decision.
