Most people don't need 4WD like they think they do. Those people also usually ride around with it in "Auto" on dry pavement and smoke the front differential by 80k miles. While I don't live up north and never will, I'd bet money quality winter tires on a 2WD will outperform a 4WD with all seasons (but obviously not winter tires on a 4WD). My great aunt live just outside of Chicago and drove a RWD Mercury Cougar for well over 10 years through the winters. I will never buy a 4WD unless it is just the right truck otherwise and it is a good deal and even then I'd consider converting it to 2WD. 2WD gets better fuel economy, has two less very expensive driveline components to fail, nothing in the way of oil pan reseals, cooler line replacements, engine mount replacements, etc. All that is to say, 2WD is a big desire for some people.
