"I have an 01 bonneville which I bought in 02 with 19k miles ($14 k) and i had several incidents ( like another review) with the car such as a connector that leaked antifreeze, the cable broke on the rear passenger window, the wheels began to vibrate, the linkage for the steering went bad, and my gas cap went bad which kept causing my service vehicle light to come on.(not covered by warranty - $26 repair).
I had an extended warranty that took care of everything (except the gas cap).
Overall, despite the issues, the car has been the most reliable I have owned. The mechanical problems that I had were not bad enough that I was left stranded anywhere or that I became upset witht the car. Vehicle ownership like housing has its hiccups. If you don't like ownership try leasing.
Even now at 76k miles it still has its pep. She can still bring it when needed. The leather seats are comfortable and still gets about 27-29 mpg on the hiway. The body's design still fits with today's style, and looks as if it were a new car.
The only thing I wish that my Bonneville had was the computer for diagnostisics on the dash and the heads up display.
Too bad GM dropped the line. I would cosider purchasing another."
Pros: "great car.....too bad no longer manufactured"
Cons: "Stopped making them :("
Likely to recommend this car? (1-10): 10
"Bought this car May 2001. Preventive maintenance always done. Window motors have gone out on each window...twice on one in back. The 1st set was replaced by warranty coverage. THE best car we have owned. Get the same mileage now as we did in 2001."
