31: Pontiac Grand Prix GXP
Also utilizing the Northstar V8 engine in its final year of production, a lot of enthusiasts don’t realize that this generation of the Grand Prix had a V8 engine. The problem with the Northstar V8 is the lack of reliability. These engines notoriously have head gasket failures, and the engine is not like the average engine to fix. While the performance was adequate for the period, the GXP was only released with a 4-speed automatic transmission This created a lot of confusion as well because the car was being marketed as a performance vehicle. A stick shift would have been a nice touch for this V8-powered sedan.

Nevertheless, as time goes on and these sedans get older with age the reliability is going to be less and less. This is a sport sedan that you should probably avoid and with good reason unless you can seek out one that has very low mileage. Pontiac was at an impasse during this period and this model of the Grand Prix was on its way out. The car was not at the pinnacle of design by any means and is probably best left avoided.
