 This car is very unreliable. Something is always breaking down. The electric wiring is messed up. First the car shut off on the freeway-no reason. Then the trunk broke and would not lock, speakers went out, then the lighter went out so I can't charge my phone during driving. Then the brake lights have been going out on & off since I've had it. Finally my drivers side lock went out -causing the alarm to go off while driving and while parked. I've been a fool and taken it in to the Arcadia dealership to be fixed which has only cost thousands of dollars. This last estimate ~$700 for a $125 part. They told me their technicians are trained that's why they charge so much. please! Never buy Mercedes. :(
