Pete,
I am loving the Wrangler. It is a bit of a fuel hog. but i knew it would be, and since it is not going to be driven daily, i can deal with that. My Cali is still my daily, and the smart is my wifes daily. She has had very little exposure to driving the smart in snow because she would always drive the Subaru(and now the wrangler) whenever we get snow. I think the smart would go OK with snow tires on it, since the engine sits on top of the drive wheels.
Like i had said in the past, my original intent was to buy a patriot but ended up with the Caliber. My son wants a Patriot. I think it is BS that we can't get the diesel patriot here. So stupid. Great economy and lots of torque with 4WD, what a great combination. Enjoy your new machine!!
