7. Pontiac GT-37
One of the rarest and most forgotten muscle cars is the Pontiac GT-37. It wasn’t a model of its own but an option package on the 1970 and 1971 Tempest. The inspiration for this model came from Plymouth. In 1968, Plymouth introduced the Roadrunner, a budget-friendly, bare-bones muscle car with wild graphics and few options. Pontiac intended the vehicle to be for younger buyers with limited budgets yet a need for performance. The Roadrunner proved to be a strong seller. Soon, all car companies started thinking about inexpensive models to attract younger customers. But for some reason, Pontiac waited until 1970 to introduce such a model in the form of the GT-37.
Behind this strange name was a regular Tempest with a few more performance options and an engine from the more popular GTO model. This meant buyers who had $3,000 to spend could get a car from 255 HP all the way to 345 HP. Pontiac advertised the GT-37 as the “GTO Lite,” but the car lacked exterior features like the famous Endura bumper and rear spoiler. For 1971, they offered the famous 455 V8, but it only went in a handful of cars. Simply put, the GT-37 had the performance and the hardware but it lacked the GTO’s appeal, resulting in bad sales. In two years, Pontiac made only around 2,000 of these misunderstood muscle cars. Today, the GT-37 is a rare sight.
