The Pontiac GTO is a legendary muscle car that was produced by General Motors under the Pontiac brand from 1964 to 1974. It was one of the brands most iconic models to ever grace the streets of America. The GTO’s success was in part to the 389 cu engine, which was the largest engine ever fitted to Pontiac’s A-body platform at the time. With sleek lines and bold styling, the GTO quickly became a cult classic and an instant hit with buyers. It was one of the first muscle cars to ever hit the market and it remained popular throughout the 1960s and 1970s. The name GTO has since been revived on several occasions, although they have had difficulty replicating the success of the original.
