 Between my wife and I we have at least 8 Mercedes. On or about late August we both leased and had delivered two 300E sedans. Hers was fine, mine  with 40 miles on it got caught on a parking bumper and the entire front came off. When I picked it up at the body shop I learned there was already the same model in the shop for the same reason, the model could not have been out more than three weeks. I was out of pocket $600 and my insurance company out $3000. I measure the front of my car and it was just under 3" from the ground. My wife's was 6", when I inquired from the dealer I was advised that warning lights come on when the car comes to a bumper. It happen again at a 1000 miles and again towed to Mercedes. Mercedes Financing and USA refused to do anything about my second event and advised from Maria at USA the warning lights come when something  in front of the car; but, not as low as three inches. So there the car sits at a dealer building storage charges and on my way court.
