If you get into car collecting because you’re trying to make money, you have to take an extremely long view of the market. That means buying up the cars you think will be valuable collectors items decades before the market decides that’s what they will be. In the Mustang market, one need only look at how much a low-mileage 1993 Cobra is going for on eBay to see what we mean.

Although picking and choosing a winner is never easy, various specialized versions of the Mustang have always been an easy bet, which is what undoubtedly convinced the late Gene Ellingsen to buy a 2010 Shelby GT500 and lock it away in his heated pole barn with just 21 miles on it. And there it would sit still. Due to Mr. Ellingsen’s subsequent passing, various vehicles that are a part of his estate–including this GT500 and several other low-mileage vehicles–were put up for auction as reported by Barn Finds.

The 2010 GT500 was in some good and not-so-good company, as it was joined by a 1967 Camaro with a 427 big-block, a 2013 Porsche Carrera, a 2008 Corvette, and a 2002 Chrysler Prowler. Also in Ellingsen’s eclectic collection were a 2000 Suzuki Swift with about 6,500 miles, a 2006 Mitsubishi Eclipse GT with 171 miles, and a 1999 Isuzu Trooper with just 51 miles.

The Shelby GT500 sold at the estate auction for $37,100 before making its way to eBay, where the winning bid topped out at $40,200. At $46,000 brand new, somebody saved them a few bucks off of MSRP, though there are similar cars with more mileage selling for as little as $30,000. Perhaps somebody else is making a bet that the Shelby’s value will continue to rise, as Shelby-branded vehicles are often expected to do.

Hopefully it won’t become another early orphan again.
