The 1991 Ford Mustang is nearly identical to all 1987 to 1990 Mustangs.
In fact, the only obvious change was the addition of a new 16 inch
cast alumnium five spoke "pony" wheels. The pattern of
lower Mustang sales continued this year dropping to the lowest mark
in a decade.
The exterior of the 1991 Mustang GT and optional on the LX used
the new "pony" wheel pictured below. It measured 16 inch
by 7 inches and features a Mustang log with red/white/blue tri bar
in the center cap. In later years the wheel was available in an
ultra rare powdercoated white finish.
Ford did remove the yellow exterior color option this
year and introduced a new Titanium Frost and a new Medium Red.
