The Pontiac GTO, like the Chevrolet Chevelle, was a classic American muscle car that debuted in 1964. Initially the GTO was merely a performance package for Pontiac’s Tempest, but became an actual separate model in 1966.

The GTO’s design was tweaked every single year of the decade it was in existence. To see how it’s evolved, we’ll rely on the excellent and consistent photography of RK Motors Charlotte, which also records 360 turntable video of the models they restore:
