Some cosmetic changes were added to Mustang II in
1977 to make the car look more sporty. One of those changes was the
addition of new bright colors. A T-roof was available, which allowed two
pieces of the roof to be removed for a more open feel, since convertibles
were still banned by the government. The same 1976 engines were available
in 1977, but with a six-horsepower decrease from the 1976 302.
The grille on 1977 Mach 1s was changed to featured
more pronounced horizontal bars, and a front spoiler was added under the
bumper. The Mach also got new four-way adjustable front seats.
The Cobra II continued in 1977, but with few
changes from 1976.
