About the Mercury mountaineer
The Mercury Mountaineer is a mid-size luxury sport utility vehicle (SUV) that was sold by Mercury from 1996 until 2010. The first Mercury SUV, the Mountaineer was a divisional counterpart of the Ford Explorer, marketed above it and between the Lincoln Aviator. Across its three generations, the Mountaineer was marketed exclusively as a 5-door wagon, with no counterpart to the 3-door Explorer Sport or the Explorer Sport Trac pickup truck.
