I honestly think now for 34 it�s an unbelievably clean c4s.

I went to look at the car yesterday evening and can confirm that it is clean example (on the outside at least).

I'd highly recommend doing the PPI and paying extra to bore scope the engine, at least bank 2.

Can one continue to use the engine with bore scoring ?
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.

Good morning everyone,
Quick intro: My name is Yann, and I’ve been a car enthusiast for as long as I can remember. Owning a 911 has always been a dream of mine, and I’m excited about the possibility. I work at the Porsche Experience Center in Atlanta, so Porsches are a big part of my life.
I’m currently looking at purchasing my first 911 and stumbled upon this intriguing offer on FB Marketplace. The car seems well-maintained with a clean Carfax, and the extensive maintenance history is definitely a plus. Here are the key details:

After researching the market, I feel the car is worth around $25k to $28k. However, I’d love to hear your thoughts and experiences, especially if anyone has insights on similar models or maintenance considerations. I did get in touch with Goldcrest motorsports and they offered to do a PPI for $495.
I plan to enjoy driving the car and working on it with my son, hopefully passing it on to him one day. Any advice or comments are welcome!
Kind Regards,
Yann
Hi Yann - this looks like a nice car. What is the seller asking? I assume more than what you're thinking? With these cars good service records > miles. I'd highly recommend doing the PPI and paying extra to bore scope the engine, at least bank 2. 4S seem to carry a premium as well so something to keep in mind.
There was a black C4S listed in the Marketplace here with 200k miles for about $25k I think. It had very good maintenance records like this one, and the car sold pretty quickly. I am not sure that the car will bring the $35k the owner is asking, but maybe somewhere around $30k would be more appropriate given the recent-ish maintenance.
However, take this as a grain of salt as I am only going off of what I have seen in my own personal search for a 996. Maybe wait for some others to chime in.
I just updated the initial post - the seller is asking $35k
thank you both for the prompt responses! I think if he's willing to go closer to $30k it may be more tempting!
Looks like it's a local car to you, so there is a lot of value in that. Go check it out, talk to the owner and get the PPI done. I think finding a middle ground between 30-35k would be fair for both sides. It looks like the previous owner did not spare expanse on maintenance so look through the records if you can. It sounds like he drove the car a good deal but also maintained it well.
Beautiful car, well documented, and local to you with good provenance.
The only red flag I see here is that the guy who coaches at Experience Atlanta is selling the C4S so he can HPDE a Camaro.
I bought my C4s after searching for a year and can chime in. The common color is downside. Huge upside is the manual transmission, interior color, assuming pccm+ (you said Porsche nav), and IMS/AOS. Prices have increased from last year and last year this is a 32,995 car. The service history that you have is worth a huge piece of mind. I honestly think now for 34 it�s an unbelievably clean c4s. That rear sonar is amazing to see too. Good luck with the Purchase.
It looks like a nice example of an 996 C4S.
According to the maintenance records it is overdue for an IMS Retrofit replacement (6 yrs). if doing this, go with IMS Solution. It is a permanent fix. You might want to consider a fuel pump replacement. The pump can begin to lose pressure as they age and the venturi pick up hoses can crack and leak. This can cause the. Engine to run lean at high rpm.
Good luck with it

I think that number is definitely a bit too high given how high the miles are $26k. Based solely on the miles. Given the ims already done and solid service records it�s a good car most likely, and ultimately it�s worth whatever someone is willing to pay for it.
I don�t know the market as well per se, but from experience currently owning a 996 C4s with 85k miles, when people say �well maintained� or PO spared no expense with a lot of recent upgrades/replacements - that can be true but it doesn�t mean you won�t be relieved of the same kind of expenses as the PO. I�d plan to be spending the same kind of money they recently have been to maintain this car, looks like about 8K every 3 years or so. Plan to have to drop 5k the minute you buy the car just to be safe, even if you don�t have to. Just my .02
I'll to the chase. First of all, beautiful C4S and the fact that it was driven and not a garage queen might pay you dividends if you decide to buy it. However, the M96.03 engines are well documented to suffer from cylinder bore scoring on bank2, with cylinder #6 being the worst. Therefore, make sure your PPI will include a bore scope inspection and get them to provide you images. Report back. All the best!!!
thanks everyone for the responses / feedback.
I'm going to see the car this afternoon and will report back. I definitely want to get a PPI done that includes bore scoring inspection.
Regards,
Yann
Let's say they do discover bore scoring during the PPI - what is the impact ? Is the only option to cylinder re-sleeving ? Can one continue to use the engine with bore scoring ?
I wonder if the current owner has a recent oil analysis report - doesn't that typically reveal early signs of bore scoring with iron, aluminum and silicon?
Good morning!
I went to look at the car yesterday evening and can confirm that it is clean example (on the outside at least). I did notice a few oil drops on the drain plug but the area surrounding it looked dry.
Initially, I wanted to get a PPI done at Goldcrest but they don�t have any availability until the 29th and that�s too long for the seller to wait. Option B is for me to get a PPI done either Monday or Tuesday at Atlanta SpeedWerks (although they quoted me $875 compared to $575 at Goldcrest).
thanks again for everyone�s feedback!
Atlanta SpeedWerks would be my choice even though it's about $300 more. They're a LN Engineering/Flat 6 Innovations certified shop. That means they've been trained on the M96 by Jake Raby and you'll get a more thorough inspection of the engine on this C4S. I've had the pleasure of meeting the owner Todd Lamb. Todd is a truly nice guy and very knowledgeable of M9X based Porsches and other German sports cars.

Hello Yann (French, maybe?)
I'm a bit confused by that maintenance line. I don't see anywhere close to 8 grand of work there. Maybe 3k?
The car you're looking at seems very, very nice. Let us know the results of your PPI and try to negotiate a good deal
Hi Yann, looks like a great car, but if you really want to know what these are selling for, you should sign up for the stuttgart market letter. It comes out every day and lists the sold auction prices for these vehicles. It gives you a great base to compare.
For some context (and I'm no expert), I paid in 2024;
2004 C4S Cabriolet
Manual Transmission
Sports Exhaust
IMS Done
No bore scoring
48,000 miles
Pretty darn good condition exterior and interior (except for the cabriolet top which was a little mangled)
$41,000USD + $2100 PPF + $800Parts + $900 winter Wheels PLUS TAX (all prices converted to USD)
Everything else I've done to the car (more expenses obviously) were my choice.
