Yesterday my witch of a mother in law threw open the front passenger door of my sportback and it was caught in the high winds we are having at the moment. As the door hit the end stops there was a horrid sound of twisting metal! I've had a quick look and so far I've not seen any visible damage. The door closes ok and the alignment still looks okay. But, given the noise it made it can't believe something is not broken or damaged. Any ideas on what I should check for?
