That's the street version of CLK-GTR, not CLK-LM. GTR had a great racing career for a couple of years before it was deeply redesigned to CLK-LM. A car with a bit stronger connection to old Messerschmitts than Daimler had expected...
so what's the main difference between the GTR and LM?
The altitude at which it operates.
I love how they make the Corvette-speedos look like they go off the scale. It's an amazing illusion.
