wrecked and replaced
Trees are not usually planted in the middle of the road which means he must have jumped a curb or driven onto some grass before finding a tree. As others have mentioned, giving him another classic car with no reprocussions probably won't be much of a learning experience which means it's likely to happen again. If he's got no skin in the game, what is there to learn? Does he pay for his own car insurance? If he didn't (or even if he did) an accident should increase his premiums unless a claim isn't going to be made. The point that needs to be made is he needs to experience some pain, which could be based on $ or time or both, to realise crashing another car should be avoided at all costs.
Tossing him the keys to that Scamp or even a Honda with no 'pain' from wrecking the Fury is a recipe for the exact same thing to occur again!
