Vehicles as large as the 2013 Navigator can sometimes disappoint on functionality. But the Navigator's plus-sized exterior doesn't preclude space-efficiency here; you'll find big seats but also reasonably good versatility and one of the best interiors of any large SUV.
Compared to the more basic models of the Ford Expedition, which the Navigator is related to, the Lincoln gets better materials and trims even though their interiors are essentially of the same design. And just like the Expedition and other SUVs in this class, the Navigator is offered in two different lengths: Compared to the standard-length model, the Navigator L adds 14.7 inches of overall length while doling out an additional 24.5 cubic feet of cargo space. In short-wheelbase versions you get at least 18 cubic feet behind the third-row seats, which is enough for a small grocery run even when you're shuttling a bunch of kids from school. Fold down the second and third rows, and cargo space grows to about 128 cubic feet in the Navigator L or 103.5 in the standard edition.
Seating in the front two rows is superb in either Navigator. With wide yet soft and supportive buckets in front, along with extra space in every direction, the Navigator has accommodations to make any large or mature crew comfortable. In the second row you get a pair of bucket seats, while the third row is where adults will feel the pinch. Navigator L versions are a bit better in entry and exit, if you're planning to use the rearmost row.
For the most part, Lincoln does a fine job giving this truck-based design a sophisticated-feeling, mostly quiet interior; though there are a few inexpensive-looking passages. We see stretches of real wood trim and fine leather upholstery, yet they're flanked by old-school switchgear, some chrome-painted trim, and hard plastics.
