Lincoln needs to apply the attention to detail wrought on the interior of the Navigator to the exterior. Outside, we grabbed the lower part of the bumper cover and tugged; the whole bumper and grille wiggled significantly. This may be to resist low speed impacts, but it imparts a sense of questionable build quality. The hood was also mounted off-center, there was inconsistency in front door fit, the left rear door fit was way off, the tailgate didn't fit flush, and the rear license plate brow trim was wavy. Inside, the sunglasses holder cover was crooked and the second row DVD bin cover was askew. Overall, however, the cabin was impressively tight with uniform gaps and solid fitments.
