Ouch indeed
I had a similar experience with Betty last year. A little 4'6" oriental female who wasn't watching the intersection and couldn't see my car in front of her late model Ford Expedition smacked Betty's behind as I was almost into the parking lot I was making a legal left hand turn into.
It took 7 weeks for work and parts, mostly waiting for parts. I had a couple of extra cosmetic items done too.
I would caution you that you might want to watch the work getting done to your car, due to the fact that you want to know the quality of repairs that you are getting. When Betty got hit, I really wanted to have the insurance company declare the vehicle as a total loss. I was, and I believe you should be, concerned with the safety aspect of having your 150+mph capable car back to it's original condition. Replacing that panel is a big job, and it requires skill that not every shop will have to do it correctly. I have worked briefly in a body shop, and I knew what facilities to look for when I chose the shop - but technicians, parts, and materials are an entirely different matter. I checked on Betty frequently when she was in their care. It's like having a child operated on. You hope you got the right doctor, etc.. I'm very happy with the bodywork that was done, but I'm not so happy with the paint job that was done afterward. I hope your experience is better than mine was.
I have pix if you're interested. Here's a link to my thread here, and I could also give you links to the threads I posted in other forums that have more pix.

I know it sucks to have your baby hurt. I feel for you. If you've considered having some cosmetic stuff done to your car, now is a great opportunity to get 'er done. It will help take some of the edge off the PITA you're gonna go through 'til this is over.:cheers & best wishes.
