To hell with the car. They are merely expendable roll cages.
As long as your boy is ok, it was a good day for junior and he just learned a lifelong lesson he will never forget. Give him a pat on the back for wearing a seatbelt [I assume].

I have thought about doing that deer drive you mentioned Bob. A guy I know did just that and killed one hell of a 9 point in that very place. Worth a shot.
