I have a daily driver here in Fairbanks, Alaska. '80 ZX NA, and it only starts to misbehave when its gets under -20F. Which is most of January and February. My only tip would be keep a close eye on everything. Running a 30 year old car through a cold winter requires much more upkeep.
I'm not sure about a turbo, but my NA 5-speed is perfectly fine on ice, but we aren't as humid up here, so ice isn't as slick as it is Wisconsin. However, I did buy my car from someone who drove it as a daily driver for 8 years in Anchorage and Kenai, which is VERY humid and VERY slick, and he said it wasn't too bad.
If you get below 0 degrees, buy an oil pan heater, block heater, transmission heater, and if you really care about the life of your car then a battery heater and circulating heater would help.
