1963 Pontiac LeMans (Best)
The 1963 Pontiac LeMans was based on the Tempest compact car, but this time the automaker decided to rectify everything wrong with the car. First and foremost, there was a convertible option now, which most consumers had opted for. The performance under the hood of the LeMans was much better than you’d expect from a car in this class (via Fifties Web).
The car only came in a two-door hardtop or a convertible model. The LeMans introduced the world to the Tempest as a midsize car, which was the plan with the model for the future. The Tempest is the car that would ultimately bring us the GTO a few short years later. Performance cars were at the heart of what made the Pontiac lineup great.
