You've gotta watch for what you're getting on the Subarus now, though.

For example, if you get an Outback with the 3.6R motor, you get the mechanical awd system with their form of torque vectoring. However, if you get the 4cylinder engine (with CVT or manual transmission), they've gone to brake-based traction control and open front/rear differentials. Having driven both systems, I'd take xDrive over the 4cylinder Outback any day.

I also made the switch...from stock Bridgestone all-seasons to a set of Blizzak LM-60s...I've never had dedicated snow tires before, but have had many 4wd and AWD vehicles, many with quite aggressive tires. The snows make a HUGE difference.
