We drove an Ultimate four-wheel drive 2007 Lincoln Navigator over a course of more than 100 miles from Asheville, North Carolina to Knoxville, Tennessee. Our test route included city and suburban roadways, as well as twisty, two-lane byways that were challenging and informative for full-sized SUV that tips the scales at over three tons. Our White Chocolate Tri-Coat model with Camel Leather was inviting inside and out. Trimmed with the Elite Package and a passel of stand-alone options, the base price of $50, 655 shot to $59,755, as equipped.
