I bought this car just over a year ago, and I still absolutely love it. I haven't had many problems... my shifter remains stuck in park, which is annoyingly solved with a key every time I start the car. Other than that, I couldn't be happier with it! After owning a 1987 Park Avenue, this is so much more fun, but it's still practical for Wisconsin Winters. I guess Pontiac could have put a little more into the interior styling. It's a little cheap feeling, but not ridiculously so.
Acceleration, fog lights, overhead console, stereo/speaker system (although I replace mine right away - personal preference), exterior styling.
