Why are so many people parking their cars over the winter? It's pretty mild here in the GRVA, no? Unless one has a fleet of other vehicles... but if that was the case, I'd presume one would have other more exotic cars to park for the winter!
I personally wouldn't be able to go 4 or 5 months without driving the M. A simple winter wheel/tire setup does the trick for me.
