3: 1973 Pontiac Grand Prix
There are very few GM cars that were hyped as much as the next Grand Prix was during this period. The 1973 Pontiac Grand Prix is downright ugly. The car was based on the same platform as the Monte Carlo and a host of other GM two-doors. Because cars were suffering from the new fuel regulations around this period, the Grand Prix just couldn’t gain leverage.
Pontiac was the performance division of the GM brand portfolio at the time. The Grand Prix was a lackluster offering and the car pretty much went downhill from here. As time went on, Pontiac was relegated to a rebranded status among the GM lineup. The Grand Prix had a lot of potential to take Pontiac to the next level. We just can’t figure out what the designers were thinking with that nose job.
