Used 2003 Pontiac Bonneville Review
Edmunds expert review
Pontiac bills the Bonneville as "Luxury with Attitude." That's an accurate description, given its basis on Cadillac's Seville platform and available 240-horse supercharged V6 engine. If traditional Pontiac styling twists your crank, and you want a large sedan packed with performance and features, the Bonneville is your kind of ride.
