2008 Cadillac CTS 4dr Sedan w/Direct Injection (3.6L 6cyl 6A)
I bought my '08 CTS in August of 2008 as a demo car, so it already had about 5k miles on it. Have had no major problems or defects. The DI engine is awesome, especially when you use premium gas. There are a few rattles that come from the dash and the driver's seat does do some squeaking, especially when the leather is cold. My only complaint has been the brakes, which started squeaking about a month after I bought it. Dealer tells me it's because of the parts used and GM should have a replacement out by January '09 - but it's May and still no way to stop the squeaking. Brakes work fine though. Overall, very happy with my purchase - it's a beautiful car, fun to drive, and a really good price.
Powerful engine. Nice interior. Very smooth ride.
Rear visibility is poor (backup assist should be standard). Thicker and wider seats for the driver and passenger. Fix the brake problem.
