What is the difference between a 1969 mustang coupe and a 1969 mustang fastback?
Coupe has a trunk and the fastback is like a sportback today (as previously answered). The fastback also offered the rear fold down seat. Its confusing as there are multiple models around these years. The Mach 1 is a fastback. It was also renames the "sportroof" in 1969 after it was launched in 1968.
