35: 2004 Pontiac Grand Prix
The redesigned Grand Prix was a completely new look for the brand. The sedan had new sheet metal and a higher performance demeanor. Under the hood, things were largely unchanged, however. The Grand Prix was still an underwhelming family sedan offering compared to the Honda Accord and Toyota Camry (via Forbes).
Although Pontiac tried to market the car as exciting, it was anything but that. There was a special edition of the Grand Prix with a Northstar V8, but this body style saw a fairly limited release. Overall, this Grand Prix was one of the most disappointing options to come from GM in a long time.
