0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Suspected cause
I suspect C4S prices to be at least $5 - $10K on average LESS than the equivalent Turbo.
Leading evidence: 'c4s prices' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'c4s prices' (1 discussions; 0 report identifying it and 1 suggest it).

Suggestion
Changing oil at least every 5000 with the proper oil (at least 40W summer) full synthetic, inspect filter, add magnetic drain plug, rev the damn thing - you will be fine.

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.

Hi all, I've been through many builds in the past from JDM to BMWs etc. and am considering a C4S near the top of my current list of cars I'm considering. Being in a C2 in the past, I miss the feel and the comfort of 90's era ergonomics (newer interiors/seats are havoc on my back, not to mention the head-forward headrests). Now, aside from the usual punch list, is there anything else I need to scrutinize, say the front diff, extra electronics, etc? Currently finalizing my purchase decision so I'd like to make the most informed decision and figured I'd ask the guys who know. Thanks!
I know there are problems with the first gen of water cooled engines. What do I need to be aware of?
I have a few locally that I am looking at and I was going to get them checked at Champion porsche here in florida as well as the obvious car fax. Are there major issues with certain years? Major TSBs I need to be aware of? If there is a site that can comprehensively teach me what I need to buy the right car, I am all for doing some reading. Thank you
I think if you browse on here and rennlist you'll find most if not all of your answers. When you have more specific questions on one you're considering purchasing..I'm sure others will chime in. Good luck on your search for a C4S! You won't be disappointed.
I have an '03 C4S and love it, as mentioned you won't be dissappointed. You really don't have any issues specific to the C4S that other 996's don't have. One thing about the C4S is that it shares a lot of components with the turbo, so if you plan on doing mods you have to make sure it fits the C4S, not just "Porsche."
If you find one post what you found and we'll go over it with you. Make sure you get a good PPI.

I suspect C4S prices to be at least $5 - $10K on average LESS than the equivalent Turbo. Engine of Turbo is based on GT1, the M96 engine has the IMSB issue - which is greatly overblown on these forums. M69 engines with low miles are to be wary of. A higher mileage engine will likely live for a good long time. Changing oil at least every 5000 with the proper oil (at least 40W summer) full synthetic, inspect filter, add magnetic drain plug, rev the damn thing - you will be fine. My '03 C4S has 95K miles and runs hard and strong. Tracked it for the first time this year (twice) and had a blast. Drove it to Traverse City MI for the PCA annual Parade and had a blast. People stop and look this car over and take pictures whenever I'm out and about - and as a bonus the insurance is less and repairs are bound to be less.
