After the Mustang had such a successful year in 1965, Ford smartly decided to leave the car pretty much as it was for 1966. The largest changes were a revised instrument panel intended to make the car more "Mustang-y" than "Ford-y," and the Mustang horse logo appearing in the center of the grill, as it has remained. The GT package was sold twice as often as in 1965, up to 30,000 from the previous mark of 15,000. Other changes included incorporating federal mandates such as seat belts, a padded equipment panel, and electric windshield wipers.
