Pontiac GTO

The Pontiac GTO was the first "muscle car". Introduced as a performance version of the Pontiac Tempest and Pontiac Le Mans, it most notably competed in the Grand National until the Oil Crisis of 1973 killed the performance car. When revived after the turn of the millennium based on the Holden Commodore the new GTO was used in the Rolex Sports Car Series, Speed World Challenge, and Koni Challenge Series. However, this would be shortlived as the Pontiac brand was already on its way out. In the late sixties Pontiac introduced a "Judge" edition which also competed in the Grand National.
