When I was stationed at Ft. Riley, KS in the winter of 87, the temp got down to -20, my car was on the north side of the house and the engine was too cold to turn over. My 883 Harley was kept on the porch and out of the weather, so it naturally, fired right away. I lived 42 miles away from the base, and it had snowed the day before. That Harley was my only transportation when I got it in Korea, but I only lived about 4 or 5 miles from the 121st Evac Hospital in Yong San, where it would frequently bottom out in the -30 or better area. On the way home from the 16th MASH, I did think about getting an oil dipstick heater for the car, so I wouldn't have a repeat performance the next day. That was one of those weeks where the high never got above -10.
To add insult to injury I got home to a ruptured pipe under the house and about a half an acre lake in my back yard, which required a plumber to come over and play.
