[Evans, Marv]

You know what?? According to your description of her, she's a great girl and you're a lucky father. So if you are giving her the car, stop fretting about any possible monetary value of it in the future. When you give the car to her, it will be her car. Even with the most careful people things happen - or not. You have no ultimate control over that or the car while it's in her possession, so don't fret about it. If you get the car back in the condition you wish for, so much for the good. If it's not quite in the condition you wished for, that's life. Just let her enjoy the car.
