Ford Mustang GT 2+2 Fastback
The
first Mustang GT was introduced in April of 1965. They
were available in all three body styles. Two optional
V-8 engines were offered with the GT with either 225 or
271 hp and a choice of a three- or four-speed manual,
or a Cruise-O-Matic transmission. The '65 GT also included
a special dashboard instrument cluster that became standard
in 1966. The GT had stripes on the lower body sides, fog
lamps in the grille, dual exhaust tips, and GT badges
on the front fenders. The GT upgrade was an extra $165.03.
