Pre-owned with 7k miles, over a year now and I still try to find any excuse to be out driving it. Acceleration is amazing, 5 years old and still a head-Turner. Few minor things went wrong but all were covered under the warranty. I drove many Mercedes, BMW's and prosches, and I can tell you this one combines the power of a Porsche with the luxury of a Benz.
too many to list
Mercedes no longer manufactures CLK cars, but I wished if the rear fender was little bit more sporty looking. And the cup-holder holds nothing, i think it should be deeper or tighter
