11 Ford Mustangs you never knew existed. Take a look at these!

Arguably one of the most iconic automobiles ever built in the United States, the Ford Mustang is already 50 years old and carries with it a rich heritage. And while we're all familiar with each generation and model of the pony, there are numerous Mustangs that some of you might have never seen or heard of. Some of them were prototypes, others are just studies that have never seen the light of day, and some were real-life models. They've all contributed to the Mustang we know one way or another, but most of them are shadowed by the productions cars we've seen roaming the streets the past 50 years.
