Richard:
There are several threads about winter driving. You may want to look through them using the search function at the top of the screen.
But here is a quick description of my experience:
I bought a set of 4 wheels and a set of 4 Dunlop winter tires. I put 5 - 40 lb bags of rock salt in the rear cargo space.
I drove my Crossfire evey day last winter, except for 2 days when the snow was more than 6 inches.
It is not an SUV, but I was able to get everywhere I needed to go...
But it is alot more fun in nice weather with the Michellins!!!!
