Initial electrical problems with the interior operating components. The local dealer was more then helpful, always providing a loaner even though I did not buy it from them. After several visits, the dealer seems to have exorcised the electrical gremlins and the car is an absolute joy to drive. I can average 23 MPG if I drive at regular speeds. However, it is difficult to do that as this car constantly asks for more spirited driving and rewards you with a well balanced and stunning performance and , even with my driving style, still returns an average of 18MPG! I LOVE THIS CAR! I have a 2003 Corvette Z06 and did not drive it all summer because I would always turn to the Mercedes for driving.
Convertible top is easy, motor and trans are totally in sync with each other, excellent handling and big reassuring brakes not to mention the AMG exclusivity that even gets attention in jaded NY
All wheel drive would make this car perfect for all year around
