The First Ford Mustang was debuted at the 1963 Worlds Fair and was the same as the 1964 1/2. However the first Mustang was a prototype in 1962. It had the distincitve air cannal on the side, but it was taller and bore futher into the panels of the car. It was originally built as a roadster, but it slowly turned into a "pony" car. One of the options for the 1964 1/2 was a picinic basket so mom could take the kids out. SOOooooo Cute ^_^
