There were only six 1999 Mercedes-Benz CLK GTR Roadsters ever built. Its beauty is only matched by its unique state of preservation, having only driven 5 miles (as displayed on the odometer) when the current owner took delivery of the car from the company. What’s even more fascinating is that this particular automobile is the first example of the design produced and the only one to sport a black livery. The roadster has an F1-inspired six-speed transmission with paddle shifters and 650 horsepower. Set to be auctioned off on June 25 via Bonhams auction house, it’s expected to sell for approximately $2.5 million USD.
