I have owned this car for 11 years and have never had the kind of problems others mention. The tires and brakes last as well as my Volvos have. Repairs are quite expensive but I go to a MB specialist who is honest and reliable for considerably less than MB dealers.
I do drive intelligently and take prope care of the car. 120,000 miles so far and many more to go.
