12. Pontiac G8 GXP
What it is: One of the best American sedans ever made
Complex Says: The whole G8 family of sedans was pretty much, along with heritage, the only reason to try and keep Pontiac around during the recession. The brilliant G8 GXP was one of the saddest losses of that economic downturn.
It was one of the last of a dying breed; the classic, V8-powered, rear wheel drive, American sedan. We truly wish this had been produced for longer, but we're happy we had it for a short while.
