The 1979 Mustang
was based on the longer Fox platform (initially developed for the 1978 Ford Fairmont and Mercury Zephyr). The interior was restyled to accommodate four people in comfort despite a smaller rear seat. Body styles included a coupé, (notchback), hatchback, and convertible. Available trim levels included L, GL, GLX, LX, GT, Turbo GT (1983–84), SVO (1984–86), Cobra (1979–81; 1993), and Cobra R (1993).
