Ford Motor Company created a performance-oriented package for the Mustang series. Known as the Mach 1, the variant is also often called as Sportsroof because of its body style. The 1971 model year came with a standard 302ci engine. The SunStar 1/18 1971 Ford Mustang Sportsroof Brown is a collectible diecast model replica of the 1971 Mach model. It has the same "Sportsroof" body style like the performance based Mustang. Its badges, grille, dashboard and other components are also from the Mustang model style.
