All you need is a good ice scraper and a battery jump pack. I also got this nice set of snow tires too, but they're rated for the summer as well so you never have to switch them out. Kinda pricey, but worth it imho. And if you drive early in the morning, you'll want to keep a cloth diaper in the door pouch so you can wipe the breath droplets off the inside of the windshield until the defroster heats up. And you'll want to drive a good car like a Volvo.
