The BMW X7 sits at the top of BMW’s SUV range, wrapping executive-level luxury and a cavernous cabin in a bold, road-commanding package. It’s ideal for buyers who want first-class comfort and presence on the road — think chauffeur-level refinement without hiring one, though you’ll need a confident approach to parking.
