On my last car, I has my 2 driver side doors bashed in by a car backing up. These days they do not beat the panels back into shape because once it is deformed the metal may crease and rust will form in the tiny cracks in the metal. They usualy change the door skins out for new ones. I find that the difference in price from the smaller shops and the dealers is not that much. The bigger shops and the dealers have to stand behind their work. If the insurance comapny is paying for it, the dealer is your best bet for repairs.
