2. Mustang Sedan – 1964

When Ford developed the Mustang in the early `60s they didn`t only make a new model but also a new class on the market – pony cars. Since there were no pony cars before the Mustang, Ford development team went in several directions and one of them was the Mustang in four-door body style. The car looked good and retained all the classic Mustang lines and proportions but Ford realized that it would cannibalize the sales of the Falcon since the Mustang was based on the same platform and with the same engines.

The reason we are glad that Mustang sedan didn`t get built is that the four-door model would have ruined the sporty appeal of the car and certainly affected the success that the original model had. A Mustang in a two-door coupe or convertible form was an exciting and youthful performance car, but a Mustang in four-door version would become just another compact family sedan with no iconic appeal.
