The 1979 Mustang was based on the longer Fox platform (initially developed for the 1978 Ford Fairmont and Mercury Zephyr). The interior was engineered to accommodate four people in comfort despite a smaller rear seat. The larger body meant the interior offered more space for four passengers, especially in the back seat, as well as a larger capacity trunk and a bigger engine bay. Two trim levels were available and included the base model and the more luxurious Ghia model.
The third generation Mustang had two different front end styles. From 1979 to 1986 the car had an angled back front clip and four headlights, known by enthusiasts as “Four Eyes,” the same front end styling that was also used on the Chevrolet Camaro from 1982 until 1992.
