Ford Mustang Sidewinder Special
For promotional purposes in the Oklahoma sales district, Ford prepared a particular version of the Mustang named the Sidewinder Special based on a 351 V8 Sportsroof model. Some experts claim the Sidewinders were based on the Mach I model but this was not confirmed (via Mustang Specs).
Ford built 40 cars in various colors and they all came with a unique set of decals packed in the box. The dealer prepared the vehicle before the sale and applied the decals. The characteristic one was the snake cartoon placed on the rear fenders. Today, these Sidewinder specials are only found sporadically.
