My Compass Limited 4x2 did great in the snow and ice this past week. Last Wednesday we got about 10", mixed with freezing rain and sleet. My ESP kicked on when necessary and did the job. They didn't plow very well, anywhere around here so I had lots of opportunities to play. I had a Matrix before the Jeep and that did pretty good in the snow, but it had low clearance, not a problem in the Compass.
I believe it's not always about the how well a vehicle does in the snow, it's more about the driver (usually). I didn't get the 4x4 because with the traction control, ESP, antilock breaks, front wheel drive and good tires, I don't need it. I'm getting a lot of grief for buying a Jeep without four wheel drive, but I have no regrets. My husband has a Dodge Hemi 1500 with 4x4, if it gets that bad I can take that, but IMO after driving the Jeep in the snow and ice this past week, I won't need to.
