Not the smartest thing I've done, but years ago I drove for nearly 3 hours in a major blizzard, 2+ inches/hour, on all kinds of roads, treated and untreated, uphill, downhill, paved and gravel, and finally managed to power through the snowbank at the bottom of my uphill, unshovelled driveway (didn't make it all the way up the hill, but it was good enough) in a Toyota Corolla. I'm sure a Civic would do just fine too.
