I own a 1996 C280( bought new) with 47,000 miles. I have a problem I never would have expected in a MB. The door panels have started to creak( best term I can come up with). They creak over small bumps, when I put my elbow on the armrest, moving the windows up and down, and sometimes for no reason at all. I feel like I'm riding around in old piece of junk. I, otherwise love this car. This is making me crazy. My first benz was a 1989 300E bought new and driven 7 yrs without this problem. Is there a fix? I'm very disappointed here.
