I've had this car since 2002, and am the original owner. Mechanically wise, this car has run well- especially for a car with over 130K miles now. Only major mechanical problems would be that the AC compressor has been replaced twice now. The major problems I've had are all small and very annoying things, like the dash warping and the dash vents breaking; the doors will lock and unlock without any prompting; most plastic pieces in the car have broken off (i.e., the mirror covers, the armrest, etc.); the paint faded in under 3 years (BAD fading on the bumpers); the doors won't shut on a cold morning; etc. Overall, the car is a good value for the money, but I don't think I'd own another one.
The car was very sporty looking when it came out, and drove very smooth and well. It is very reliable and the warranty may be worth overlooking the little problems.
New dash material, which I see the new Spectras already have. Better interior materials, better paint.
