I purchased my Acheiva SC in the Fall of 2001. It currently has over 100,000 miles on it and I really haven't had to do much repair. Three years ago I did have to take it to a shop and have some kind of thing replaced, not really sure what was wrong with it, but my car just would not start. First it would show all of the lights on the dash i.e. security, oil light, ets, emergency brake, all those lights would come on. Then one day it just died. So that cost me about $1,400 bucks.
Pre-existing was the passenger side lock does not work, but that's no big deal. Also, non pre-existing the driver's side window has fallen off the track (manual window) and you have to literally manually lift the window up.
At the moment, my air conditioner does not work, it has not worked for sometime, but I have not yet made an effort to get a diagnostic performed to see what it is. I'm getting that done this week and hope its just low on freon!
The alignment is kinda off too. But I think that may be from a little fender bender I had and that was one thing that was not fixed when taken to the body shop.
Overall, considering this was the first car I have ever purchased, it has been considerably reliable. The problems I have had with it are expected, it was a used car after all. I wouldn't mind purchasing a new car and when that day comes, I think a part of me will miss this car. Its been a pretty good car and esthetically its not too bad. It drives well, handles well, and has great performance (get up and go!).
