We've had one snow storm come through, but it has since melted. As long as its not too cold out I will drive my Mustang. I just installed Nitto N55R's, and they suck below 40 degrees. But my Mustang is on a battery tender all year around since she only gets driven irregularly, and even though she is garaged, my garage isn't insulated so it does get damned cold in there. However, my Mustang actually has a factory block heater installed as she originated from Wasilla, AK. Anybody else have this factory option?
