I plan on purchasing Subaru this year either a Forester, Outback wagon or a Baja. There seems to be a lot of snow during the ten months of winter up here, ranging from 36"/ year in Chaumont to 100"/ year around Tug Hill Region. Most of my driving will be on plowed, but not cleared roads just below freezing. My daily drive is 30 miles each way. Is there very much difference between the Forester and the Outback/Baja in performance in the snow? Is the high output engine needed for towing? What options should I purchase and put on, besides an engine heater for the -40 degree days. What about tires? Any thing to change? Size or tread pattern? Are there any really good online or catalogs for parts?
