We leased the car in Feb. We have had nothing but problems. The lifters in the engine had to be replaced because the engine knocked.They didn't fix it and they wanted to replace the blocks. The transmission wouldn't shift right. They had to replace the fuel lines which took forever becuase they came from Germany. They finally are taking the car back. I dont think all Mercedes vehicles are bad but you get lemons in anything. We bought this one because our last Mercedes S400 was totalled in a flood after we owned it for a month. We must be destined not to own a Mercedes . Still liked the styling of the car, the comfort and versitility.
