How to equip a car for snow?

Get snows on all four wheels, get windshield washer fluid that has a very low freezing point, get a heavy duty ice scr and brush. Change the oil to a thinner weight (5W30)- oil thickens up when cold, lastly a more powerful battery. As for the BF's car, same thing, he may have to get a different set of rims for the snow tires tirerack.com can help with this.
