Coming fresh on the heels of the two other Bosses, the 302 and 429, the 351 is one of the rarest breeds of Mustangs out there. In 1971, the only year they were made, just a pinch over 1,800 were assembled and sent out into the world.

Some still call it a facelift, but that doesn’t even begin to describe all the changes.
