Reasoning:
1) Even with snow tires, the Z isn't meant for snow and will suck compared to a normal FWD car.
2) You should really have a set of winter rims for the snow tires, so now you're looking at a lot more $ than just the rubber.
3) Even if you don't actually skid out and crash, do you really want to subject your Z to all the salt, cinder and calcium that eats paint and causes rust?

Metaphor:
Just because you can use a scalpel to cut firewood doesn't mean you should. Use the right tool for the job. Flame suit on.
