By now, plenty of places north of the equator have had serious snow, so if you want snow shots, get out there. Be careful, though; don't let yourself get hurt, and don't hurt your car.
In the Christian world it's the Christmas season. Does your town have a big Christmas tree which you could park your car in front of for a shot? It's a little corny, but you could put a big bow on your car for a shot as well.
Also in the northern hemisphere we're at the very shortest days of the year. If you've got a bulb setting (let's you lock the shutter open) and a tripod, get night shots. Especially if you can include the sky, you'll get nice star tracks over your car (see below).
