Pontiac GTO

1964 Pontiac GTO, shown at a classic car meet in Sweden in 2015. The one that lit the fuse. GM limited its intermediate cars to 330 cubic inches, so Pontiac sold the GTO as an option package on the Tempest LeMans and got a 389 V8 into it anyway, with Tri-Power carburetors on the options sheet. Spot a 1964 by its quad headlights set side by side; for 1965 Pontiac stacked them vertically, and by 1966 the GTO was a model in its own right.
