This is one of the first 50 examples of the Mustang Boss 429 that Ford built largely by hand for its most important dealers. Barrett-Jackson noted it’s fitted with the rare, 375bhp 820-S NASCAR engine and a specific suspension, among other equipment that helps it stand out from later cars. It sold for $605,000 in 2007, which represents approximately $748,000 today. In hindsight, it was a terrible investment. RM Sotheby’s sold the same car for $275,000 in 2013.
