My lease is almost up and I was thinking about getting an SUV. I've been asking around and it seems SUV owners are a fanatical crowd. I'm mainly interested in snow/ice performance. I might do light off-roading just because I own one, but that wouldn't be a determining factor. Is AWD the same as 4WD? If 4x4 better or worse than any of those? Why should I care about a crossover vs 'real' SUV? Bfun must own one, living in Colorado.
