No matter HOW nice it is/was, it's just a car. You can buy another car, but you can't buy another son and thank God, according to you, he's ok. THAT's what's important to keep paramount in your mind. You've received some good advice already- let YOUR carrier deal with the third party's company; that's part of what you pay insurance for. I'm sure you'll be treated fairly, but don't sign a full and final release until a couple of weeks at least, to make sure everybody is ok. Keep us posted.
