I own a 1996 993 Cabriolet Tiptronic C2.
I've owned it for a little over a year.
Its an awesome car and its my daily driver.
Its my daily driver because it has powered everything and AC.
Its also alot quieter for Business cell phone calls.
The maintenance on it is a hassle considering you don't have to adjust the valves.
It has two oil filters that are a bitch to get to and the list goes on regarding other things.
Look for low mileage, maintenance receipts, etc.
Get a PPI from some place you trust.
Don't trust Car fax etc.
Make sure all fenders, hood etc. line up.
If its been repainted be very afraid.
Test everything electrictal in the car.
Especially the top if its a cabriolet.
Check out
http://p-car.com/ for more information on maintenance etc.
If you have other questions let me know.
I love the car and I will never get rid of it as long as I'm employed.
If I got layed off I would sell the 993 and keep the 914 because the 914 with the 3.2 still puts a bigger grin on my face.
The 914 handles better and its still faster to 140 mph.
