2005 Pontiac Bonneville

Once known as GM’s performance brand, Pontiac was discontinued in 2010 along with Hummer, Saab, and Saturn. The legendary GTO of the 1960s and Firebird of the ‘70s, ‘80s, and ‘90s were joined by models such as the Grand Am, Grand Prix, and Bonneville, which were based on other GM models. The Australian-built Pontiac G8 was a legitimate muscle car, and the Vibe hatchback shared its design with the Toyota Corolla Matrix. Today, most Pontiac vehicles still on the road are more than a decade old and lack the safety and convenience features found in modern vehicles.

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.
