Buy a cheap fridge for the garage. If your garage sees the action mine sees (buddies, kids with bikes, etc.), its gonna take a little abuse. Buy a unit that your not gonna mind if it gets a little dinged up here and there. Also, I live in Detroit so our weather is pretty much the same...in the winter I turn it off. Its plenty cold to keep everything in the fridge ice cold. If you plan on using a freezer, its kind of a bad situation. In the summer, your freezer will run and run but if your garage is hot like mine, nothing will stay deeply frozen. In the winter, its so cold that the freezer will rarely run. Again, items will be partialy frozen. Hope this helps!
