So here's my pile, a 2005 Pontiac Bonneville GXP. This car truly is everything wrong with GM in the early to mid 2000's. Needlessly complicated, front wheel drive, large as a barge, unreliable, impractical, not very class competitive, and has no real target audience. This particular example has roughly 109,000 miles on the clock and already has an engine rebuild under its belt. This engine really is the cherry on top of this lemon; the notorious 4.6 liter Northstar V8 delivers 275 untamed torque-steering horses to the front wheels. This car truly was a recipe for disaster--doomed from the start. If your GXP wasn't plagued with head-gasket issues, the infamous Bonneville rust would claim it. And with a production run of 2 years, only around 6,000-8,000 units were ever made, and I'm sure many, many less are still on the road today. While the Bonneville GXP is slowly being forgotten with time, I'm here trying to keep its rather flawed and unfortunate legacy alive.
