I have a 2002 SLK32 AMG and the aluminum sill/scuff plate has a indentation in it that I would like to attempt to straighten out. If someone can tell me how to remove it without causing any damage to anything else. I wasn't sure if I could gently pry up on it, or do I have to remove the plastic piece it's attached to and get to it from underneath. Also, when opening and closing the doors there is a slight bump, or resistance in the motion. I tried to lift up and down on the door to see if maybe a bushing was bad but that's not it. I didn't know if this was normal or not. Thanks in advance.
