"the car doesn't even look that badly damaged" Are you serious man? The bottom of the door frame is smahed in right where he was sitting, doubt a seat belt could do any help in this case, direct impact with body. As for the parts of the car, My wife knows how much I love my Z but she would'nt want it just sitting out back rusting away and reminding her of the wreck. She said she would let someone buy it for parts and I agree with her. I do agree though that now is not the time to contact the family or anything. I hope that he has a close family friend that will take care of it. Thats what I would want. AGAIN, Condolences go out to his family and friends.
