Watch the video below as a 1967 Ford Mustang Shelby GT500 Sells For $2.2 Million Dollars at Mecum Auctions in Kissimmee, Florida.
The car was a one of a kind prototype that Carroll Shelby had built for a tire test conducted by Goodyear.
The 428 V8 engine was swapped out for a racing version of the 427 V8 from the Le Mans GT40.
Top Speeds were up to 170MPH.
There were talks of a plan to build 50 of them and sell them to the public for close to double the price of a regular GT500 but after consideration and lack of interest nothing transpired.
The vehicle had roughly 26,000 miles and had changed ownership hands several times.
The closest sale to date previous to this sale was $1.3 million in 2013 for a 1968 EXP 500.
