Sir Stirling Moss may have departed this world, but his legacy lives on, not only for his numerous race wins across various forms of motorsports but through vehicles such as the Mercedes-Benz SLR McLaren Stirling Moss. The historical predecessor to the likes of the Mercedes-AMG GT R Roadster and forthcoming Mercedes-AMG ONE, the SLR McLaren was a supercar collaboration between Mercedes-Benz and McLaren before the latter got back into proper road car production.

But the SLR Stirling Moss was the most special of this breed, a limited-run supercar of just 75 units built with speedster styling much like the McLaren Elva. When it went on sale in 2009, it carried an asking price of $1,000,000, but with so few in existence, it's not often that one comes up for sale. Until now.

One of the 75 Stirling Moss models has just come up for auction at RM Sotheby's 'Open Roads, The European Summer Auction' event. Located in Germany, at the time of writing the lot currently has a bid of 950,000 euros ($1.085 million) on its proverbial roof. But with three days left of the auction, Lot 250 is expected to fetch big, big money, with estimates of $2.5 million expected when the hammer drops.

Some might consider that an absolute bargain considering this particular Stirling Moss has had just three owners and has covered less than 5,600 miles from new.

Built to commemorate the 300 SLR that was campaigned by Moss in the 1955 Mille Miglia, the SLR Stirling Moss is an open-top speedster with slick bodywork and immense power. The supercharged 5.5-liter AMG V8 engine under the hood produces 641 horsepower, propelling the Stirling Moss from 0-62 mph in just 3.5 seconds and on to a top speed of 220 mph. It was a stylish, lightweight machine that shaved 441 lbs off the weight off the standard SLR, courtesy of extensive use of carbon fiber in the bodywork, aerodynamic package, and the underside of the car.

This particular iteration is a European-spec model finished in Antimony Grey Crystal over a black leather interior with red accents. Considering we may never see a modern version of the SLR McLaren, for someone with deep pockets this could be a once in a lifetime opportunity.
