The Mercedes-Benz SLR McLaren 722 S Roadster has the makings of being a future classic thanks to a combination of high performance and a production total of just 150 units worldwide, and now you can buy one for the eye-watering price of £1.1 million. Picking up the supercar should be a treat because it's currently in the Mercedes-Benz Museum in Stuttgart.

The SLR resulted from a cooperation between Mercedes and McLaren, and production took place at the British brand's base in Woking, England. Using the SLR Roadster as a starting point, these models have the improvements from the 722 Edition that boost the output of the 5.5-litre supercharged V8 to 641bhp. The droptop can hit 62 mph in 3.7 seconds, which is amazing by 2009 standards and still impressive today. The vehicle could reach a top speed of 208 mph.

This one has an exterior in the shade Crystal Antimony Grey, and there's a semi-aniline leather interior in black with contrasting red stitching. Plenty of carbon fibre decorates the cabin. 

This one has 16,031 miles on the odometer since the initial registration on April 27, 2009. There have been two owners previously.

Unlike its contemporaries like the Ferrari Enzo and Porsche Carrera GT, the SLR was more of a high-speed grand tourer than an all-out supercar. While capable of over 200 mph, they were better as cruisers due to the five-speed automatic gearbox. The 722 variants also received carbon-ceramic disc brakes, lighter 19-inch wheels, larger front splitter, and revised rear diffuser.

The car is for sale from All Time Stars, which is Mercedes in-house service for selling its vehicles. Each one goes through a 160-item checklist prior to the sale.
