I'm in Maryland as well and quite honestly I walk when its bad out, I'm a mile from work. I did drive a bit in what was left last winter after they plowed and I had no problem but then again I've had practice in a Corvette, a couple of 280 and 300 zx's. I think its not so much what you drive in the snow, its how you drive. If you have no experience then you will have problems, get a beater as someone suggested. I would not recommend this car in any kind of deep snow. Around here they do a really good job of cleaning the roads, my issue is the amount of salt they use doing it. I'm a clean freak and the salt scares me on my car. I purposely stay off the roads until it clears up a bit. I had no problem with the snowy and icey patches I hit last winter.
Best of luck this winter,

Pat
