Rear ended 66 cuda advice

Well, my daughter was rear-ended today while stopped at a red light on her way to school. The shop said the frame will have to be straightened, rear pass qtr replaced, trunklid replaced, front clip, etc. Car hit her from rear about 20 mph, pushed her into car in front of her, damaging both ends, and dropping tranny fluid and coolant out of the radiator. AC condensor gone as well.

In all likelihood, the car will be totalled. I had it appraised (and insured) about 1.5 months ago for $10,000, and have since put another $3,000 into it. The wreck was not her fault in any way, as she was stationary at the stop light, so the other girls insurance is liable.

Any suggestions on how to proceed to assure that we are adequately reimbursed? I have over $11,000 in the car, having just 2 weeks ago put in new front seats ($820) along with rebuilding the OE 273 ($1800) .

Any suggestions, tips, hints, etc. on how to insure I get the best payout from the ins. co? I don't want to profit, just to be reimbursed for the money i have in it.

Thanks!
