Summary

This 2021 GLS450 offers a refined entry into the flagship Mercedes SUV experience, combining a smooth 3.0-litre inline-six with a mild-hybrid system that excels on long GCC highway stretches. With 53,411 km on the clock, this five-year-old vehicle has been driven well within the typical annual mileage expected in the region, preserving its mechanical longevity. The Black exterior is a top-tier choice for resale in the UAE and wider GCC, ensuring strong value retention when it is time to upgrade. As the 'S-Class of SUVs,' it provides a level of cabin quietness and road presence that few rivals can match, making it a perfect fit for family road trips across the Emirates.

This Car vs Other 2021 GLS450s

At 53,411 km, this GLS450 has covered roughly 10,700 km per year, which is significantly lower than the GCC average of 20,000 km for large family SUVs. Being an American spec model, it offers the same high-level luxury equipment as local units but at a more competitive entry point. The Obsidian Black finish remains the most sought-after color in the regional used market, directly supporting its future trade-in value.

4MATIC vs Lower Trims

The 4MATIC trim is the standard-setter for the GLS range, providing the essential AirMatic air suspension system that allows for adjustable ride height—perfect for clearing speed bumps or lowering the sill for easier loading. While lower-trim GLE models often lack the third row, this GLS includes a power-folding 50/50 split rear bench as standard. It also features the upgraded Burmester surround sound system and ventilated front seats, which are non-negotiable for summer comfort in the Gulf.

GLS450 vs Segment Rivals

The GLS450 leads rivals like the BMW X7 and Audi Q7 in usable cargo space, offering a generous 355 litres of boot volume even when all seven seats are occupied. Its long 3,135 mm wheelbase provides superior legroom in the second and third rows compared to the Audi Q7. For long-distance driving between cities like Dubai and Riyadh, the Mercedes emphasizes a softer, more isolated ride quality than the sport-tuned BMW.

Running Costs & Resale

The 3.0-litre mild-hybrid powertrain averages approximately 11.0 L/100km in combined driving, though GCC highway cruising can see this drop toward 9.2 L/100km. Mercedes-Benz maintains a massive authorized service network across the UAE, Saudi Arabia, and Kuwait, ensuring parts are always readily available. While European luxury SUVs typically depreciate faster than Japanese alternatives, the GLS holds its value better than almost any other vehicle in its class due to high demand for the S-Class badge.

Performance & Capability

A 0–100 km/h sprint of 6.2 seconds is remarkably swift for a vehicle of this size, ensuring effortless merging onto fast-moving UAE highways. The 48-volt EQ Boost system provides an extra 21 hp and 250 Nm of torque in short bursts to eliminate turbo lag during overtaking. With a 7,700 lb towing capacity and standard all-wheel drive, it is fully capable of handling weekend excursions to the desert fringe or hauling a boat to the marina.

Comfort & Cabin

The interior is a sanctuary of tech, centered around dual 12.3-inch MBUX displays that provide high-resolution navigation across the region. Standard four-zone climate control ensures that even passengers in the third row stay cool during peak summer months. The cabin is insulated with acoustic glass, significantly reducing wind noise during high-speed highway travel between the Emirates.

Safety

Standard safety features include a 360-degree camera for easy parking in tight mall spaces and blind-spot monitoring for safe lane changes on busy highways. The Pre-Safe system and active brake assist provide a vital layer of protection for family occupants. Adaptive LED headlights with high-beam assist ensure excellent visibility on unlit desert roads at night.

The bottom line

This is a low-mileage, high-spec family flagship in the best possible color for the local market, making it an ideal choice for a buyer who wants S-Class luxury without the new-car depreciation.
