This Mercedes has been the least reliable vehicle I have ever owned. The electronic engine control hooks to an antitheft interlock which fails randomly. The dealership is happy to take my money but unable to solve the problem. Hence I can be anywhere and try to start the car and have it disable the vehicle, leaving me stranded. The Mercedes club people know of this problem and tell me that Mercedes made a replacement computer that disables the lock out, but will not sell it to me. The us Mercedes people were uncooperative. Since I bought the vehicle used, they state that someone could have changed my computer before I bought it. Yeah, sure.
rides well when it runs, but terrible on ice and snow, not a car for midwest winters
remove the antitheft interlock, put in a pressure relief valve for the radiator, the plastic cap failed on mine and destroyed the radiator
