You know what I say. It's not so much the snow that's a problem. It can somewhat navigate snow depending. It's the ICE!!! Ice and this car's current tires are a no go. Get some dedicated snow tires & wheels or don't drive this car in those conditions or you'll be sorry.
At the end of the day, do you really want to take that kind of chance of "MAYBE" you won't slide into another car or object and have $$$$ worth of damage....
