9. Ford Mustang Sidewinder Special
For promotional purposes in Oklahoma sales district, Ford prepared a special version they called the Sidewinder Special based on the 351 V8 Sportsroof model. Some experts claim that they based the Sidewinder on the Mach I model, but Ford has not confirmed that.

Ford built 40 cars in various colors, all with a special set of decals in the box. The dealer prepared the car before each sale by applying the decals. But the most characteristic one was the snake cartoon they placed on the rear fenders. Today, those Sidewinder specials are rare.
