Cold weather, most cars aren't a fanS

So this has been a heck of a winter over here on the east coast. I live in MD and we got slammed a few weeks ago before xmas and then again a few days ago. So far my little diesel has been chugging along just fine through the winter even down to zero degree mornings but a few days ago apparent the inside of my intercooler got a little icey and thawed just enough to where my car choked on some water. It seems to be okay again now even today where it was 7 degrees.

I was seeing how all of your vehicles are holding up to this extreme cold weather ?
