1966 Ford Mustang

1966 Ford Mustang Fastback â?" Silver, 4-Speed, Inline Six with Period-Correct Detail Throughout Why This Car Is Special The 1966 Ford Mustang Fastback is one of the most recognizable shapes in American automotive history, and the fastback body style is where the design logic is most convincing. The long roofline sweeping into the rear deck gives the car a proportional completeness that the coupe and convertible simply do not have. Ford sold just over 499,000 Mustangs for the 1966 model year across all body styles, but the fastback â?" officially called the 2+2 â?" accounted for roughly 35,000 of those units, making it the least common of the three body styles that year. That scarcity is part of why fastbacks consistently command more attention in the collector market than their coupe counterparts.
