I daily-drove a rear-drive Alfa Romeo Spider for 5 Boston winters. Then drove a rear-drive Mercedes E300TD for another 4 Boston winters (though that one I at least put snow tires on). You learn pretty quickly what the car can and can't do; even on summer tires (and a limited-slip differential), the Alfa would go until it got high-centered on the snowpack. Either would handily out-perform my current Nissan LEAF (FWD) in the snow. LEAF factory tires are designed for economy, not winter traction.
