2008 S40 2.4 L Engine: Snow and mountains?

I live where it snows and near the mountains, and am considering this car: how does it do in snow? What about going uphill with 4 people and ski equipment? The engine is sort of small.

I'm considering a used model for about 27k Canadian with about 30,000 km. It was a loaner vehicle for a dealer ship and then it might have been leased to someone.

Is this a good deal?

Thanks.
