I rolled my Saturn SL2 a couple of years ago and tore off the mirror. As I recall, the mirror, a new wheelbearing, and repainting the rear door was a little over $500 and the mirror was the least expensive item. I think you are talking $100-$200 installed if I am remembering correctly (Saturn's are very modular, so this should be a simple repair). Let us know how it goes. It is possible that they just need to reattach the mirror.
