2002 Cadillac Seville STS 4dr Sedan (4.6L 8cyl 4A)
I have owned my 2002 STS for three years and love it...sort of. I'll be honest the engine and tranny work great together. Throughout my time owning it I have not had to have the engine or transmission serviced. The interior looks great (it won interior of the year in 1998) especially with the newer nav unit but it does suffer from the GM rattles and cheap plastics. The real problem with this car is it's suspension. Tie rods and intermediate shafts seem to be a recurring problem. Having 300HP going to the front wheels puts a lot of strain on those weak legs. I love my car and thank goodness for warranties.
Performance, navigation unit, heated seats, Xenons, back up sensors and all the other Cadillac ammenities
It's already been done, but RWD is the main thing. What's the point of having 300 horses if you can't control them? The rattling plastic is annoying.
