The sales of the Mustang are a multi billion dollar business. Ever since 1964 Mustang has played a leading role in the automotive industry. The Mustang will not ever be replaced.

In just the first two and a half years their where 1,288,557 Mustangs sold. Mustang was a dominant automobile with no competition until Chevrolet came out with the Camaro, Pontiac the Firebird, and Plymouth . Ford's response to that competition was a new, slightly larger Mustang with an all-new body over what was pretty much the same chassis.

The standard power plant was now the 200-cubic-inch six making 120 horsepower: with a 250-cubic-inch 155-horsepower six and the 200-, 225- and 271-horsepower K­-code 289 V8s optional. New on the menu was a 390-cubic-inch "big-block" V8 breathing through a Holley four-barrel carburetor making 315 horsepower. Accommodating that wider engine meant that the front suspension's track needed to be widened by 2.5 inches for clearance.
