I have owned a '94 Bonneville since 1996 and have over 200,000 miles. My son drives it now. The 3800 is an excellent engine!
My daily driver is an '02 Bonneville (base model), white with gray cloth interior. Nice ride, quiet, smooth, but gas mileage is not what I was hoping. 22-23 mpg combination driving. I've only owned it for 5 months.
Previously, I owned an '87 Bonneville and it had 175,000 miles when I sold it and it kept going for several years. I'm telling you, the 3800 engine is a trooper!
My real passion is for muscle cars. I've owned several Pontiacs: 2 Firebirds, 1 Trans Am, 1 Firehawk (current), and a '71 GTO. My current project is a 1970 Cuda. I am pretty solid GM/Pontiac but you gotta admit, Cudas are cool. A member from a Firehawk boards invited me to come here and check out the Bonneville site. I guess there is a site for almost all cars? (Even the Pacer?)
