The overview
Pontiac's top sedan is lively with the available supercharged 3.8-liter V6, though you don't need to opt for this top-level engine to get plenty of power. It was redesigned for 2000 and was significantly improved, with taut handling, a supple ride, and optional stability control. Despite the positives, the Bonneville doesn't possess the refinement of some other cars in its class. The front seats lack support, and the rear bench is too low and soft. The 2004-05 GXP features GM's Northstar V8 engine. Discontinued after the 2005 model year.

Behind the data
Latest source update: September 11, 2026
Vehicle summaries, specifications, pricing and ratings come from Consumer Reports vehicle records. Auto Guide groups these records by model and reported generation start year.
Available years are listed explicitly. Gaps do not imply that a model was discontinued. Prices are source estimates, not live offers. No first-hand road test by Auto Guide is claimed.
