The door handle on the driver's side in the front broke off. I had to pay through the nose to get if fixed. It was like plastic. I am 5"1 and weigh under 130 pounds. I am not strong enough to break it and I also have ra. I never slam a door in anger. I really like my car but wonder if the rest of it will fall apart. I was in the garage. I have the broken piece.

I was driving to work from parkville to baltimore city and my car began aggressively jerking. I drove my car on friday morning through the tunnel and the jerking was not as aggressive. I drove home on friday afternoon from work and I could tell that something was still jerking but continuously. Saturday morning my car was jerking so aggressively, I called owings mills mercedes and left it there. I was notified today, may 27, 2015, that my car needed between $1900 and $7500 worth of work. My coolant is leaking on the transmission. If my radiator can not be fixed, I will need a new radiator as well as transmission.
