When do you report your TT’s before winter – and do you even report them off?

I think I’m going to send mine to hibernation at the end of October. When do you do it ? Or do everyone go through the winter ? I know Quattro is certainly horny in the snow but to me the car for all the salt and the bumps and scratches through piled up snow hills is just too bad. In addition, a set of winter bikes costs as much as a reasonable winter car.
