That's an easy one.
Sell the car towards the gnarliest, ugliest, yet most reliable looking older toyota you can find. It will be what you drive in the rain and snow so choose wisely.
Take the cash you have left over to trade in your bike for a 600 you've been aching for. Stop being a cager and get something you'll LOVE. Aprilias are always nice. Ducati's never look bad. A triumph wouldn't hurt.
Take the plunge man, A red Ferrari 599 GTB doesn't hold a candle to the coolness of even the slowest old sportbike.
