I hate threads like this. If I one the $500 millon powerball on wed, I'd get whatever and however many I wanted. specifics would not matter, b/c you have the money to buy them all.
I'd buy a house close to every racetrack I"d ride regularly, stock the garages with whatever trackbeasts I'd want to flog, bikes and cars, done! Oh, hire someone like Kato, to be the houseboy to watch things.
