I have never had a FWD or AWD anything. Various trucks on all season tires, an old Miata a couple winters ago on Blizzaks, and I have always gotten through winter just fine. Would I drive my Mazdaspeed Miata coat it with salt and risk ripping off the air damn, no. Would I drive my Camaro and never get anywhere, no. A lot of RWD cars do fine, but if the car handles rain well, it'll handle snow on appropriate tires well. For example my Camaro would slide around in the rain easily when it was stock, even with snow tires I doubt it would be very good, however a Miata is still really controlled in the rain and having driven one on snow tires I can say that it will work fine.
