If one car epitomizes the sixties muscle car phenomenon, that car is the Pontiac GTO. Like the Mustang, which was also introduced in 1964, the GTO happened to be the right car at the right time. The GTO concept – install a large passenger car engine in an intermediate body platform – was fairly simple, but its success was due to good timing: the public was ready for a smaller performance car. Within a year, emulators abounded, with other General Motors divisions offering their own versions of the GTO, but the original outsold them all.
