Do you have snow tires? Living in a snowy region, I've learned that nothing makes as big a difference as snow tires -- whether the car has stick, automatic, AWD, whatever. Admittedly, it's hard for me to directly compare stick and automatic because the cars with automatic were also much heavier -- a minivan and a SUV.
