The mid-1960s experienced a major boom when it came to muscle cars. Many die-hard followers of American Muscle credit the 1964 Pontiac GTO as being the first true muscle car, wherein a car has a large motor shoehorned into a mid-size car. Several automakers followed suit and created their own muscle car versions of their regular model lineup, and General Motors was at the front of the pack when it came to this new trend.
