Stuart you suck.
j/k... When i store cars over the winter, all I do is disconnect the battery, and forget about em til spring. I've never had any fuel problems, or flat spotted tires, or any of the other horror stories everyone always starts talking about around this time of year. I uncover them, put the battery cable on, run the starter around a few times, fire it up, and change the oil in the spring. I do recommend keeping the tank near full during the winter, as in the springtime as the weather starts to fluctuate between warm days and cold nights, sweat and condensation can form in the tank and mix in a little water with your gas... keeping the tank full seems to prevent this.
