Mustang Mach 1 - 1971-73
This style of Mustang is still considered as "Generation 1", though if placed side-by-side with a 1965-66 Mustang I personally see a considerable difference.
By 1971-73, the Ford Mustang had evolved into this style. This one is the SportsRoof fastback model on which the backlite was about as horizontal as imaginable. There were notchback and convertible models as well. Though still considered as the 1st Generation of Mustangs, these were about 3" wider than even the 1969-70 versions and were the largest and heaviest of Generation 1. Departing from the original concept of a light, sporty-looking compact 2-door that was embodied by the 1965-66 Mustang, Ford executive Lee Iacocca, the man most associated with the Mustang's creation was reported to have said about the 1971-73 models, "The Mustang market never left us, we left it."
