I have been able to drive up almost 3000 ft in elevation on my commute with 2008 SX4 in up to 12 inches of unplowed powder. (not wet snow which we don't get much of luckily). The sketching/super steep part required the differential lock. When my SX4 is done (hopefully not for a long time, 155K right now) are there any other cars, crossovers, small SUVs that come with a differential lock. Thanks.
