NH sees real snow...the kind that can be on the roads for 2-3 months.
You want a fun little sedan/wagon with dedicated snow tires if you have to do serious driving up there. I'm a subaru fan for such a task.
While you can outfit the Z with snows, but they still are a wide tire and not the best when it comes to snow/ice traction. You want a skinnier tire on smaller rims for that.
