1996 Pontiac Bonneville Reviews
Bought this car brand new, and just sold it at 200,000 miles - my auto tech said it would easily last another 100,000 miles. Great car with lots of features that are not on my 2004 bonneville. Some rust along the bottom of the doors - very minor. Otherwise, was in great condition.
I bought this car at 1 1/2 yrs old. It was a lease car with 43,000. I now have 280,000 miles on this car and still love it. No major problems, I keep oil changes and maintenance done regularly.
