Can't speak for the CLK but I am well pleased with my recently acquired SLK350. Goes like the clappers! Am averaging 27.6 for mixed driving, after one month. I reckon a heavy CLK500 will be not be much quicker in a straight line and nothing like so nimble on a winding road. I looked at a CLK (but not the 500) and they are a lot bigger than the SLK and it was space I didn't need. As others have said try 'em both and go for the one you like! Good luck.
