The GLS63 combined seven-seat practicality with AMG’s twin-turbo V8, and this one has covered moderate miles. It carries 21-inch AMG wheels, Airmatic suspension, a panoramic roof, active LED headlights, a Surround View camera, massaging front seats, heated second-row seats, and a receiver hitch. Bidding stands at $10,000 with six days remaining at no reserve.

What it’s worth right now
Data from Carfax shows 2017 GLS63s listed at $34,907 with 39,331 miles and an accident entry, $39,700 with 70,126 miles from one owner, and $29,170 with 58,935 miles. Cars.com puts the average 2017 GLS63 listing at $28,780.
Its mileage places this one toward the top of that range. The 37,000 miles, clean Carfax, and fresh tires help, while the absence of listed service records, the cost of Airmatic and twin-turbo upkeep, and auction pricing temper the number. Fair value lands between $32,000 and $42,000, with $37,000 most likely. No reserve means it sells.

Condition and details
The specification is extensive. The SUV wears Designo Diamond White with a panoramic roof, active LED headlights with curve illumination, running boards, roof rails, and a power tailgate, and it rides on 21-inch AMG wheels with Bridgestone Alenza tires dated 2025, Airmatic suspension, and adaptive damping.

The cabin is well equipped. Black AMG Exclusive Nappa covers the heated, ventilated, and massaging multicontour front seats and extends to the dash and doors, with heated second-row seats, three-zone climate control, heated and cooled cupholders, and COMAND navigation with smartphone integration.

Documentation is thin. The seller bought the SUV in 2024 and has added 20,000 miles, and only manufacturer literature and two keys accompany the sale, with no service records listed. The Carfax shows no accidents, and the North Carolina title is clean. A pre-purchase inspection should check the Airmatic suspension, the turbochargers, and the oil service history.

What makes the Mercedes-AMG GLS63 unique
The GLS63 was Mercedes’ full-size, seven-seat SUV with AMG’s 5.5-liter twin-turbo V8, combining family-hauling space with sports car acceleration. Its Airmatic suspension and luxurious cabin made it a favorite among buyers who wanted performance without giving up practicality.

These SUVs depreciate steeply, which makes them strong values used. Running costs remain high, particularly for the air suspension and turbochargers, so documented service history adds confidence. Lower-mileage examples with clean records bring the best prices.
My take
At $10,000 with seven bids and six days to run at no reserve, my call is $37,000, with $42,000 possible if bidders value the low mileage and Diamond White finish. What makes it appealing is the package, since a 37,000-mile GLS63 with massaging seats and seven seats delivers AMG performance for family duty. What tempers it is the lack of service records. Request any available records, then bid.
