I can't recall if it's been mentioned or not, and I'm not reviewing the whole thread to find out, but I would seriously consider a Mazda 3 were I looking for an efficient practical 4x4.
Have to admit:
Ground clearance might be a little low for deep snow, but a good set of Hakkas will get you by most storms, plowing snow with the air dam. I would just settle for the front wheel drive 2.0 L. Noted, the standard 155 HP seems a little weak after driving a fun car all summer (now driving the 2012 version of same), still preferable to the 186 turbo in the GT considering reliability and fuel economy.
