It's one of just 40 right-hand-drive CLK DTMs built
A special version of the DTM racing car, this road-legal Merc CLK was built in very limited numbers in 2004. 100, to be precise. And of those 100 Coupes released for sale - via special order or an invitation of ownership - just 40 cars were built with the steering wheel on the correct side.
Unsurprisingly, they sold out pretty fast. Which means trying to find one is quite difficult.
