These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I am looking to buy a manual 996 C4S and wonder if there are any particular mechanical/performance/finish quality issues that I should be aware of? I am looking at cars from 2002 through to early 2005. Any comments that you can provide to help ensure I get the best car for my money would be very gratefully received. Thanks.

POST 2Original post

Andrew!! There is a buyer's check list here which you might find useful: http://www.porscheclubgbforum.com/fb.asp?m=269468

POST 3Original post

Only advice is to get a check done by OPC or an Indy. Money well spent could save you a lot of money and heart ache. Things to look for are Rear Main oil seal (RMS) and front rads. But a Check is best advice. 996 C4S are fantastic cars.

POST 4Original post

Welcome! Check the inside edges of the brake disks for corrosion, front radiators for damage/corrosion (collect leaves and debris), check aircon, check for oil leaks (rear main seal) on underside of engine... Best thing to do is to get a PPI done (OPC or independant) - Personally I would also pay £120 and get the cylinders checked out for compression and an internal visual inspection with an endoscope camera. If all the above checks out you will have a great car!

POST 5 / ORIGINAL POSTEROriginal post

Great, thanks very much to you all. An OPC check seems to be the way forward.

POST 7Original post

Hi, As stated above, buy one[ ] Nothing more to say! Regards Alan

POST 8Original post

I've had mine for 4 years now and has now got 26000miles on the clock faults i've had are main light switch, n/s radiator, & battery replaced. Try to buy a car with full service histoy more the better. Pick what opptions you would like to have on the car eg sat nav, tel, sport seats, aero kit, etc etc Then take your time and the right car will turn up good luck
