The guy wanted $3500 for the 72 and he thought it was a Mach 1 because the salesman told him that in 72. The engine compartment was a time capsule still had every factory sticker and even the letters that you see on concours cars on the firewall. The drivetrain was the only thing of value 351 CJ 4speed and locking 3.25 rear. The hood had separated from rust and the floors crunched when I touched them. The last 71 I saw was a lime green with black stripes in Hampton VA for $2000. Needed total resto. They are nice looking rides restored.

From "Mustang Special Editions". In it is a page and 3/4 long article about the 1971 "Special Value Package", also known as the "Spring Special" or the "Sport Coupe". They made 9,003 of them, all coupes (obviously), and all engine options were available.
