This is my second Bonneville, first in 1984. Nice sturdy vehicle.interior is adequate comfortable. Good solid brake system. Transmission went out at 90,000 miles. Ok except for the computer system which has problems. Smooth running. Replaced the serpentine belt at approx 90,000 miles. Replaced the catalytic converter & exhaust system at 140,000. Heating & A/C run great, no problems so far. Suspension is great, power steering rack went bad, have to add fluid periodically. Overall, a very reliable vehicle..
This is my 3rd bonneville. I started with the 94. All have been the ssei (super charger). The 94 definitly had the most power! I think they must have later, put a govener on them. On my 2000 and 2003 I have had repeated problems with the steering. It clunks and grinds. They have a defective part in them that you can replace, but it eventually does the same thing with the new part. They have a bad front end design. The seat heater went out in the 2000 and the 03. The car looks good, rides great, has good performance, but definitly has mechanical issues. Also had a leak in the intake manifold, ended up installing a new crank and bearing. Guess its a common problem with these.
