Prices for the GLS start at $75,950 for the 450. Getting into our V8 tester requires at least $98,800, and getting a GLS exactly like the vehicle featured here means cutting a check for $119,950. Most of the $21,000 in options feels worthwhile, though.
As covered, the $6,500 E-Active Body Control and $2,250 Driver Assistance Package are smart buys. If you’re regularly planning on hauling other adults, you might as well splurge for the $4,400 Executive Rear Seat package (heated/vented/massaging rear seats, a rear wireless charge pad, and “comfort” headrests). And if you live somewhere snowy, go for the $1,050 Warmth and Comfort Package (heated front and rear armrests). The $1,100 head-up display and $1,000 panoramic sunroof are a bit dear for a vehicle that starts at $100k, but by and large, there are few bad options on our GLS.
As for the competition, a V8-powered BMW X7 is cheaper, starting at $92,600, while the most affordable V8-equipped Range Rover demands $105,950. The real bargain is the Lincoln Navigator, though, which is only available with a 450-horsepower, twin-turbo V6, but at a price of just $76,185. You can score a range-topping Navigator Black Label for $1,665 less than the GLS 580’s starting price, even.
Adding options doesn’t much help the GLS compared to its chief competitor. A fully loaded BMW X7 xDrive50i is available for about $115,000, almost $5,000 less than our well-equipped tester.
