Older model years carry meaningfully higher accident rates, so always verify the vehicle history report on pre-2020 models.

• Safety package: standard driver-assistance features include lane-keep assist, forward-collision warning, automatic emergency braking, blind-spot monitors, stop-sign and traffic-light recognition, speed-limit tracking, and adaptive cruise control with stop-and-go functionality.
• Infotainment: the standard Superscreen is three 12.3-inch screens in one dashboard-spanning housing, running a new version of the MBUX infotainment system based on Mercedes’ own MB.OS operating system, developed in-house.
• Fuel efficiency: Mercedes expects the six-cylinder GLS 450 to achieve 21 mpg combined (19 mpg city, 24 mpg highway) in EPA testing.

• GLS 580 4Matic: adds a twin-turbo 4.0-liter V8 with 530 hp and 553 lb-ft of torque, plus the large Mercedes star in the grille center and stronger straight-line performance for buyers who want more power.

The pattern also suggests that the GLS is giving up value at a fairly steady pace rather than showing sharp exceptions in one direction or another.

The 2017, 2021, and 2018 model years have held their value best, with the smallest year-over-year price changes.
