I am in Columbus, and spent 10 years in Youngstown before that.
I have driven an ADAMO, Puma, and ENVEMO Super 90 in the winter. They all had roll-up windows, and none of them had anything more than stock heat (via heater boxes) There were times it was pretty rough! I now have a Spyder and Speedster, and bought a '82 300D to drive in the winter as my "beater" From experience, if you can afford to drop a few grand on a "winter beater", do it!
