I've lived and worked in the DC metro area my whole life. No need for x-drive. People in DC can't drive in the snow and will crash into you. It doesn't snow enough that that roads aren't cleared within 12 hours. The traffic jams that result when 3 flakes hit the ground are not worth sitting in. If it snows just stay in and work from home.
BMWs are great with just a set of dedicated winter tires. It's less expensive to just run a set of winter tire on separate rims for the winter months if you have that much concern over it.
