Hi guys, and welcome back to my channel. The full-size, three-row luxury SUV segment is intensely competitive despite the relatively low volumes. Just take the four major players in the category as an example. The BMW X7, Cadillac Escalade, Lincoln Navigator, and Mercedes-Benz GLS. All four have been completely redesigned in the last 2 years and all are incredibly advanced machines with a lot of luxury, status, and space. But which is the best of the four? Join me as I go through an in-depth review to give you the answer.
