The Lincoln Navigator serves as Lincoln's full-sized luxury SUV. The Navigator shares the same platform with the lesser Ford Expedition full-size SUV. Introduced in 1998, the Navigator has proven extremely popular, comprising 40% of the American luxury SUV market in 2001. It is the larger of the two truck-based SUVs produced by Lincoln in the early 2000s, the smaller being the Aviator (which becomes the MKX for 2007). While the current 2006 Lincoln Navigator ranges in price from roughly $50,140 to $67,645, the new 2007 Lincoln Navigator will feature a price range of $52,990 to $66,545. If customized, the Lincoln Navigator's price can range to well over $100,000.
