 After I brought the car home, foundout there is a long scratch on the side of window, the dealer's pre-sale service sucks, they did not even inspect the car !After 3 weeks, the car was less than 1500 miles, the car's steelring wheel quit working during the middle of the turn, almost killed me by kissing the light pole...I had mercedes during the 90s, I can not beleive their quality and service gone so low .I would never buy another Mercedes.I had a Acura RL for years and I never had any problem with it, its quality, comfort,safety and equipment are way better than Mercedes, and 20k cheaper too.
