Not long before Ford unveiled the Mustang in 1964 at New York, the concept version was grabbing the headlines. Following the Mustang I concept's debut, Ford set off to build a more realistic concept that would be much closer to what it had in mind for production. Compare the Mustang I and II concepts and you'll notice dramatic differences. Much of the second concept's styling and its overall layout made it to production, and the Mustang was born. But what happened to the concepts?

The first one is located at the Henry Ford Museum in Dearborn, Michigan. The second is at the Detroit Historical Museum, and car spotter DtRockstar1 has exclusive footage of it being driven on the road.
