Which X5?

[gwinder]

I am finally breaking down and selling my LandRover Disco1 and decided to look very seriously at the X5. I live in Michigan so we do get quite a bit of snow and I primarily want the car for winters as I have a Boxster S for the summer. So with the snow in mind, which X5 should I get? I don't do that many miles...maybe 4K a year so the fuel usage is not an issue. Is the X5 3,0 heavier enough or should I go with the 4.4? Also, I noticed reading the threads that quite a few people put snow tires on suggesting these cars don't handle too well in cold weather?

Appreciate anyone's input.
