Used 2004 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 275-horsepower Northstar V8. 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.

What's new for 2004

The supercharged SSEi version of Pontiac's luxury tourer is no more, but a V8-powered GXP model makes its debut later in the model year. This most performance-oriented of Bonnevilles, the GXP, gets more streamlined styling (less cladding, that is) and comes with 18-inch wheels, a sport-tuned suspension, leather/suede seats and a Monsoon sound system. Aside from that, chrome wheels are now available on the SE model.
