I had this happen once with Avis in France. I actually did ding the side view mirror, and when I returned the van, I told them about the damage. Unfortunately when we picked up the van it already had two huge scratches running the whole length of the van, which I took pictures of, and so naturally they sent me an invoice for repainting the whole side of the van. I tried with their customer service to work it out, but they just gave me the runaround, so I disputed the charge with my credit card and I never heard anything about it after that.
