When it was released in 1998, the CLK-GTR was the most expensive production car ever built, with a tag of .5million. It marked Mercedes' return to Le Mans following a seven year absence, although the race car didn't win the 24 Hours. The 6.8-litre engine delivered 720bhp, resulting in a 0-60 mph time of 3.8 seconds and a top speed of 200 mph. Only 25 were ever built for the road.
