 '08 CL63 is my 7th MB and by far the best - came out of a SL55. Love the Drive Dynamic seats -simply amazing, as is the Distronic. I can get 2 adults in the back in comfort which is unusual for a coupe. Was going to buy a Bentley GT.  Head turner, great interior, wished I had bought the CL65 however as performance won't make your eye balls bleed. As is typical with MB - early problem - had to replace my back window as rear window defroster didn't function. I drive this car 12 mo - put 4 winter wheesl/tires on it; quite acceptable traction and handling in snow.
