Maybe this would have been a good weekend to test a Land Rover. I’m staring at a grille-high wall of snow, plowed overnight across the end of the icy Adirondack driveway. On the other side is a snowy country lane, and maybe oncoming traffic—I can only see straight ahead because of the mountainous snowdrifts piled on all sides. I’m pretty sure the locals are breaking out the snowmobiles today. I try the safe, slow approach and end up stuck atop an icy little barrier. Fortunately, this 2008 Mercedes C300 sport sedan, which I’m driving for my weekend in the country, crawls out easily in reverse. After confirming that I can ram out into the road without hitting anything, I get a running start, plow through the snowdrift, turn hard to the left and brake, skidding onto the road; I can feel the gentle percussion of the antilock brakes as we glide to a soft, abrupt stop.
