Well, its 95% his money, 50%my time and they are his keys even thou the cars in my name for insurance reasons.( he was only 16 when he bought it, 17 now.) But we do squeal the tires as much as we can get away with. I never go nuts with it UNLESS he tosses me the keys and says "you give her a run dad !" Then he really smiles...ok, maybe we both do alot of smiling.
