He emailed me scans of quotes ranging from $800 to $1500. The lower quotes were from shops that said that they could fix the existing panel, whereas the higher quotes were from shops that wanted to cut/replace the entire panel. I'm going to take a look at the car next week and make my decision. Its a high mileage 540i 6speed but the deal is good enough that I think it would be worth the headache. Even after fixing the damage the price I'm looking at is well under blue book.
