2002 Pontiac Bonneville Reviews

Dad drove 130k in 2.5 years w/ no problems. I have had it for 5 years and 50k miles and no problems other than normal maintence.

This is my last Pontiac, I'm trading it in on a Camry. I bought Pontiac's top of the line, the Bonneville. I bought the SE version. The engine has a great sound, and the acceleration is excellent. I bought it with 22k miles on it, and in 7 years, I have it up to 58k miles on it. In that time, I've replaced 2 window motors, the intake manifold, the strut mounts, wheel bearings, and the secondary steering shaft twice, and the brakes more times than I should have had to given the age and miles.
The steering shortly after I bought it got to be creaky. It pretty much has stayed that way.
The buttons on the interior are cheap, and the paint has worn off the radio buttons. There are a couple of rattles on the interior.
The car handles great, rides very well, and has plenty of power. I like the looks, it's just typical of GM, lots of promise with poor execution.
