If you don't have the right tool for the job, sometimes you can force the wrong tool to "make do", but you wouldn't buy the wrong tool intentionally.
A subaru would be limited by ground clearance in "heavy" snow, but would be far better than the Prius. For the deepest snow, 4x4 with high ground clearance would be best. AWD cars would be ok for light to moderate snow.
Every CO license plate I see in MD is attached to a subaru.
