The original "pony car," or personal coupe, and the greatest marketing coup of all time: Ford sold one million Mustangs in less than two years, which was a record at the time. The brainchild of Lee Iacocca, the original 'Stang was launched as a notchback coupe or convertible in mid-1964 as a 1965 model (often called the 1964½) on a 108-inch wheelbase. At first, unspectacular sixes and unmodified Falcon underpinnings made for a package that was in reality pretty unremarkable, but available 260 and 289 V8s nearly made up for the car's chassis shortcomings. Later versions saw updates that fixed many of the handling issues seen in the early cars. Mustang's first generation saw several redesigns, starting in 1967, and again in 1969 and 1971.
