The 2008 Lincoln Navigator hits the most important marks for a full-size sport-utility vehicle. It's relatively smooth, quiet and huge both inside and out. It comes equipped with lots of safety features and nearly all the luxury bells and whistles. The Navigator's tow rating is among the highest in the class, and it runs on regular gasoline where nearly all others require premium. The base price is lower than most of its competitors, before dealer incentives, but its sister vehicle, the Ford Expedition, can be equipped with almost as much luxury at a considerably lower price. Some will find Navigator bland. Those who regularly transport lots of passengers and stuff, and those who tow heavy loads, should find it worthy.
