I hope your okay and glad your to the point you can type about it. Good thing it wasn't the Z.
I say they will try to fix it. I've heard, that if both air bags deploy they will total it. That may be a rummor though. Get detailed pictures and make notes on what is messed up other than the obvious.
If anything was broke before the accident blame it on this accident. You deserve something for your trouble.
I had a motor mount from a wreck that I saw was bad. I scribed a big X in it and sure enough they didn't fix it. When i went to pick up the car it was still on. I pitched a fit and they replaced it.
Looking back I would have marked more parts and took better pics. I traded it in not to much longer after that. I know that feeling your describing.
Good luck, and at least your alive.
