I traded the 996 yesterday for a Mercedes S430. I got 26k for the 996 with 47.5k on the clock. It needed new rear tires, the driver door glove box door replaced, the steering wheel leather needed some cosmetic work and the wood on the center console replaced.
The S430 was 27.2k with 51k miles on it. I got a 12 month warranty because the car is certified and I bought two more years for 3.7k. Warranties are getting more expensive.
I'll be starting posting on the 944 and S class blogs from now on.
