The origin of the Boss 429 comes about as a result of NASCAR. Ford was seeking to develop a Hemi engine that could compete with the famed 426 Hemi from Chrysler in NASCAR's Sprint Cup Series (then known as "Grand National Division"). NASCAR's homologation rules required that at least 500 cars be fitted with this motor and sold to the general public. After much consideration, it was decided by Ford that the Mustang would be the car that would house this new engine.
These cars are highly coveted and super rare. As of 2008, auctions on eBay and at Barrett-Jackson have brought bids of over $375,000. In 2013 an unrestored Boss 429 Fastback sold for $417,000 at auction.
