In the winter? My Porsche 924s. Perfect 50/50 weight. at around 3000lbs it has enough weight. I put 4 cooper snow tires, not all season but true snow tires on it and it is great in the winter.
The key to any car in the winter is getting real snow tires.
If things get really bad (say 18-24 inches of snow and the plows are no where to be found) I use the expedition. It just does not care about snow. In fact with the AWD system combined with the stability/traction control system actually rides / drives better in the snow than on dry pavement.
An interesting side bar to this that with those systems it seems to be critical to keep the tires inflated evenly at all four corners. The manual has different inflation pressures front and rear but I have found that this seems to make the ABS / traction control / stabilitrak systems fight its self. the truck seems to be fighting its self during acceleration and deceleration. Don't know why this is. It may be unique to my truck. If I keep tire pressures even all the way around and the drive line feels more free.
