How bad does a wreck hurt your car resale value?

I have a 2010 Toyota Corolla S with about 10000 miles on it. Well, about three days ago a woman was reading her receipt and not paying any attention while she decided to run down the side of my car. Damaging the rear driver side bumper and tail light, the under skirt, scraping both drivers side door, broking the mirror off, damaging the wheels and tires. The dealer called today to tell me that the estimate damage ran about $4300. He told me that they will have to replace the rear bumper, both door skins, tail light, and the skirt and then they can repair the rest. Is there a way that I could tell them to replace that whole side? Would repairing parts decrease the value of the car rather than replacing the parts? Thanks for the help
