I feel for you and I feel sorry for the girl too, but do her a favor and don't let her get away with this. I had a similar experience.
A young guy maybe early 20's ran a stop sign and hit my wife's eight month old car that was parked in our driveway. He was spinning his wheels when I came out of the house trying to back out, but he was caught up on a stack of logs he had ran over. He had been drinking and was begging me to not call the police, saying he would pay for the damage. Too late for that, the neighbors had called them when they heard the crash.
The cops showed up and took him away and towed the guy's truck out of our driveway. My wife's car was drive-able but badly damaged, about $5,000 worth. People who knew the guy told us he was a nice boy, just drank too much. We let the insurance company fight the court case and we just stayed out of it. We heard afterwards he cleaned up his act and gave up drinking.
Looking at the crash site afterwards we realized that if his truck had been just one foot over to the right, a tree branch could have taken his head off. As it was, his truck roof scraped the branch, but the ground was lower where his wheels hit.
