 2001-C240, 165,000 miles. I will NEVER, NEVER, NEVER, EVER buy another Mercedes. 1) I had to unplug the power seats because they drain the battery if left plugged in overnight. 2) Automatic trunk opener does not work. 3) Sunroof does not open properly. 4) Cup holder does not work. 4) Dash lights do not work. 5) It sounds like either the rear bearings or the transmission is going out. 5) Poor gas mileage (20-23 mpg). 6) two spark plugs per cylinder. Each spark plug cost $20.00. 7) The rear window shade does not work properly. 8) Cigarette lighter does not work. I do not smoke but I need it to keep my phone charged. 9) CD changer does not work properly. 10) The radio will shut off on its own but if I open the passenger side door the radio comes back on. A mechanic told me that the engine will last forever but the rest of the car will cost you your house! I have a 1995 Toyota Camry with 395,000 miles on it and everything still works.
