I disagreement with your disagreement.
I lived through a decade of winter one year in Chicago when I had a (at the time brand new) 1973 Formula 400 Firebird. It, and cars like it have to be about the worst possible vehicle to have in snow....rear wheel drive; lot's of HP/Tqu and with more weight on the front end than the rear (where you need it for traction)...I survived it but I'd never do it again; at least not willingly.
Can a 370 be a year-round car even in the snow belt? Of course.
It won't be fun but it can be done - if you've got other options I'd use them
Rain is also something people should be mindful of...the tires on the Z
are WIDE tires and really only truly good in dry, summer conditions...it doesn't take much water for you to hydroplane right off the road and what's even worst is that you'll probably never know until your in the ditch so please folks, SLOW DOWN when it rains and arrive alive (and without need of a tow).
