I have a FWD GT, I put snow tires on all my cars, AWD is a waste. This car, like all my other cars with snow tires, is actually FUN to drive in the snow.
AWD does nothing for turning or stopping. The stock 20" tires look marginal at best for the snow. 17" wheels with Blizzaks from the Tire Rack for $1100, including another set of TPMS. Much cheaper than AWD, don't have to suffer the weight, performance and MPG penalty of AWD for the 99% of the time the car isn't driven in snow.
I can see AWD drive if you live in an isolated area or have a really long, steep, shaded driveway. Otherwise, just no reason.
