Now that the two-year no-sale clause has ended for some Ford GT owners, we're expecting to see more examples of Ford's flagship supercar looking for new owners. Recently, a limited-edition 2017 Ford GT '66 Heritage Edition became the first-pre-owned GT to be legally sold at auction for a whopping $1.54 million. This Ford GT for sale, however, is considerably rarer.

Currently listed for sale on Bring a Trailer is one of around 40 Ford GT Roadsters in the world. Based on the previous-generation model, the Ford GTX1 was built by Genaddi Design Group in Wisconsin but was fully approved by Ford. It was introduced at the 2005 SEMA Show as a nod to the GT40 X-1 that won the 24 Hours of Sebring in 1966.

This particular example is the 33rd GT that was converted to a roadster by Genaddi Design Group. The owner had it finished in Mark IV Red over its aluminum body panels and had the racing stripes removed. During the conversion, Genaddi Design Group also added a four-piece carbon-fiber roof panel, a revised engine cover, removed upper door portions, and headrest fairings. This Ford GTX1 rides on 18-inch forged-alloy front wheels wrapped in Bridgestone Potenza RE050 tires.

Power is provided by a supercharged 5.4-liter V8 that was given a Ford Performance upgrade during the conversion as the owner was one of the first ten customers to place a deposit for the GTX1. It comes paired with a Ricardo six-speed manual transaxle with a helical limited-slip differential. With the Ford Performance upgrade, the V8 has been uprated from 550 hp to 700 hp. Inside, the GTX1 features silver-grommeted Sparco racing seats and branded floor mats and doorsills. Since it was bought in 2006, it's clocked up less than 12,000 miles.

This is a chance to own one of the rarest and most fetching Ford GTs ever made. At the time of writing, the current bid is $215,000, but we wouldn't be surprised if the final selling price is at least double that since we've seen other GTX1s listed for sale for over $500,000.
