What Edmunds Says

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.

Pros

Loads of gee-whiz features, solid handling and drivetrain, excellent crash test scores, large trunk.

Cons

Average interior materials, overly complicated controls, poor resale value.
