Sedans are also less desirable as more and more people drive SUVs -- it makes it hard to see traffic and it's more dangerous when you are the lowest person on the road.
I hope you're putting on the correct type of tires for snowy days. A lot of those models come with summer/performance tires which are incompatible with snow. For my S4, I have a set of Bridgestone Blizzak snow tires that I use during the winter months.
So fun
