Sorry guys, I can't agree with the OP that this is the worst car I've driven in the snow. In fact, I have to say it's one of the best because I can slide the shifter into Sport Mode and stay in a lower gear longer.
As for the stock Continentals, yes, they're not the best (like the DWS model) but it's good enough I think. Just don't drive fast in the snow.
Currently I have the entry-level Goodyear Ultragrips that Ford gave away with the purchase of a new vehicle and they're really decent as well.
