The Mercury Mountaineer is a mid-size luxury sport utility vehicle (SUV) that was sold by Mercury from 1996 until 2010. Sharing many of its features with the Ford Explorer, the vehicles were virtually identical in terms of hardware. Externally, they were styled somewhat differently, and the Mountaineer was positioned with a more upscale interior, with the Mountaineer's MSRP coming in at $1,000–$6,000 more than the Explorer. It was last redesigned for the 2006 model year with a new frame, looking very similar to its previous model.
