The Explorer continues to be the best-selling sport-utility vehicle in the country. It isn't necessarily the best, SUV in the country, at least if real off-road capability is a factor. Modest ground clearance and a long wheelbase, limit its usefulness in truly rough country. What seems to keep the Explorer on top is its roominess, solid reputation, for durability, quality engineering, good looks and its overall reputation as the leader. Those are the things that, keep resale values up. This Explorer XLT sports leather, 4x4, 20 mpg and plenty of room for 5 passengers plus cargo.
