If you have a spare £1.1 million, you've just missed your chance to own a 2005 Mercedes-Benz CLK GTR Coupe and a 2006 CLK GTR Roadster.

The rare sports cars - only 20 coupes and five roadsters were built - were sold at a recent RM Auction in London. Managing to beat earlier estimates, the coupe went for £522,500 while the roadster sold for £616,000.

Built by HWA, the GTRs were powered by a monstrous 6.9-liter V12 engine with 612 horsepower. The cars also featured a six-speed sequential manual gearbox, a dual independent double-wishbone suspension, and carbon-fiber brakes.

Other notable sales at the auction included a "1950 Aston Martin DB2 Team Car with Le Mans and Mille Miglia provenance" for £550,000, a 1969 Mercedes-Benz 600 Pullman Landaulet for £308,000, and a 1938 Bugatti Type 57C Stelvio for £440,000.
