Have you tried good snow tires?  Good ones really do make a <b>huge</b> difference over all-seasons.

I admit, it's not the same as 4WD in terms of pushing you forward where the front wheels are pointing - but often snow tires will be better at stopping, which most people believe is pretty important.  8-)  Of course, good snows plus 4WD is better for the average driver.

I often buy from TireRack, since they have a huge selection, and even with shipping costs, their prices are still comparable to local shops.  They have a <a href="http://www.tirerack.com/tires/surveyresults/surveydisplay.jsp?type=W&VT=C&sortValue=16" rel="nofollow">winter tire comparison, too</a> (no affiliation, just a satisfied customer).

Good luck in any case, whatever you end up driving!  And if you still have the energy, feel free to give the salespeople heck.
