Though it might be hard to imagine, back in 1970 Ford officially pulled factory support from all of its motorsports teams, leaving many teams high and dry and forcing them to pull out of competition. But not the famed Bud Moore, who still had four body-in-white Kar Kraft-built Boss 302 Mustangs on hand.

Now one of those cars, which has a long and storied racing career, is heading to Mecum’s Monterey Auction next month, reports Hemmings Auto Blog.

As the story goes, Moore converted three of the four body-in-white Boss 302 Mustangs into race cars for the 1971 season. Even without factory support, Moore was able to enlist Peter Gregg and George Follmer to race two of the Mustangs (the third being backup). Gregg finished seven of the eight races that year, and placed in four, including a runner-up to Follmer at the Byar 200.

This Mustang would go on to change hands numerous times over the next few decades, undergoing several extensive restorations and taking part in numerous vintage car races. It was last sold for more than $400,000 in 2009, and could easily bring that much when it hits the auction block next month. It still amazes us how much these old race cars are still worth, though we’d probably pay a lot of money just for a few laps behind the wheel. Would you?
