Noooo! You need a quiver, just like skis!
Seriously, the very best solution is two vehicles. One is a 4x4 with four studded snow tires (Toyota 4x4, of course). The other is your favorite RWD sports car/sedan with performance all-season tires that do well in the snow, just in case. Just like your skis, you pick the vehicle for the conditions. With just one vehicle you are compromising performance like you do with a 98mm ski!
Yeah, I know it sounds excessive, but it's really not if you have two slightly older, less expensive vehicles. Rather than one $30K vehicle, get two older reliable $15K vehicles. Yes, you'll pay more for insurance, but you'll make up for that with less depreciation.
This is the correct solution, of course, because it's what I've done for years.
