Great car! Comfortable, smooth, quick and gorgeous. Prior MB was an AMG SLK. Faster than the SL but not nearly as comfortable or luxurious. We leased the SL and wish we'd bought it. The 39 month lease is up this year and the purchase option is outrageous. Don't like the looks of the '09 nearly as well as the '03 through the '08. About the only thing we don't like (other than a very poor radio and non-intuitive controls) is the cost of routine maintenance. For the price of this car MB should include routine maintenance as BMW/Audi do. We're hoping the '10 model returns to the more classic style of the '03-'08. If so, we'll buy one this time.
Looks, performance, comfort and, of course, the retractable hardtop.
Include routine maintenance cost in the purchase price of the vehicle. Improve the radio. (The Bose system in this car is an embarrassment). Copy the Lexus in terms of intuitiveness of the various controls. We've had the car for over 3 years and still have trouble trying to use them.
