What are the potential issues? 2800 for this vehicle. Thoughts??? very well maintained....
Welcome. We bought our daughter a 2002 Bonneville 2years ago. We have the same issue with the fuel gauge. It has never been accurate as well as the speedometer. The electrical system is q little wonky when it comes to the windows. Other than those issues, no mechanical problems. It also is immaculate. My husband did some research on them and found that these are common with some of the Bonneville'*. We couldn't have picked a better car for her. It also had just over 160,000 miles on it. Good luck to you.
