A Tempo is my winter car. It'll start no problem at -40F, not plugged in, provided I didn't put E85 in it.
At -40 I'll let it idle while I scrape the windows then get in and go. It's about 1/2 mile down my residential street to any roads so when it's that bitter cold I'll put it in 1st or maybe 2nd and just idle down the street. Once I get on the road and I see the temp gauge needle starting to come alive, I get going.
