Summary

This 2020 Mercedes-Benz GLS450 4MATIC represents a balanced entry point into the pinnacle of the brand's SUV lineup, specifically configured for the GCC market. While the mileage reflects a history of consistent long-distance use, this is often a sign of a vehicle that has been maintained to highway standards rather than subject to the wear and tear of low-speed urban congestion. The grey exterior is a highly practical choice for the region, offering excellent resistance to showing desert dust while maintaining a strong resale profile in the UAE and wider GCC. As a GCC-spec vehicle, it provides full peace of mind regarding cooling capacity and service compatibility at authorized centers. For a buyer seeking a legitimate seven-seater that doesn't compromise on luxury or highway composure, this specific GLS offers a significant value proposition compared to brand-new equivalents. The 3.0L turbocharged inline-six engine is widely regarded for its smooth power delivery and improved reliability over previous generations, making it a sensible long-term choice for a regional family vehicle.

This Car vs Other 2020 GLS450s

With 189,000 km on the odometer, this vehicle has more mileage than the average 2020 model in the GCC market, which typically clocks around 80,000 to 100,000 km. However, in the context of the UAE where highway commuting between Emirates is standard, this figure indicates a car that has spent the majority of its life at stable operating temperatures on well-maintained roads. The grey finish is an ideal middle ground for the region; it avoids the heat absorption of black while offering a more sophisticated look than common silver, ensuring it remains an easy-to-sell asset in the future. Because it is a GCC-spec model, it retains a distinct value advantage over the American-spec imports often found in the used market, which may lack the necessary transmission cooling or radiator capacity for our peak summer months.

4MATIC vs Lower Trims

As a 4MATIC model, this GLS features Mercedes-Benz’s sophisticated all-wheel-drive system as standard, and in this specific trim, it includes several essential luxury upgrades that lower-tier SUVs lack. Buyers in the GCC will particularly appreciate the inclusion of the Burmester Surround Sound system and the MBUX Infotainment system with augmented reality navigation, which were often optional on base models. This trim level also ensures the presence of the 12.3-inch dual-screen cockpit, providing a seamless digital experience that remains current with even the newest models. Furthermore, the 4MATIC designation includes an enhanced air suspension system (AIRMATIC) that is vital for maintaining ride quality when the vehicle is fully loaded with seven passengers and luggage. You also benefit from higher-grade interior materials and ambient lighting that significantly elevates the cabin atmosphere during evening drives through the city.

GLS450 vs Segment Rivals

The Mercedes-Benz GLS is frequently cross-shopped with the BMW X7 and the Lexus LX570. While the Lexus offers legendary reliability, the GLS450 leads significantly in terms of interior tech, ride smoothness, and fuel efficiency thanks to its modern 48V mild-hybrid assisted engine. Compared to the BMW X7, the GLS offers a more usable third row and a more cavernous total cargo volume, making it the preferred choice for families who genuinely need to transport seven adults. Its cooling system is also specifically engineered to outperform European rivals in high-ambient temperatures, ensuring the rear-most passengers remain as comfortable as those in the front during August drives. Additionally, the GLS offers a more compliant on-road ride than the body-on-frame Lexus, making it far better suited for the high-speed highway transit that defines GCC driving.

Running Costs & Resale

Real-world fuel consumption for this 3.0L 6-cylinder engine is impressively efficient for an SUV of this size, averaging approximately 10-12 liters per 100km on the highway. In the stop-start traffic typical of Dubai or Riyadh, the mild-hybrid system helps mitigate fuel waste by managing the stop-start function smoothly. Maintenance is straightforward across the GCC, as Mercedes-Benz has an extensive network of authorized service centers like Gargash and Emirates Motor Company in the UAE, and Juffali in Saudi Arabia, ensuring parts are always readily available. While European luxury SUVs depreciate faster than Japanese alternatives, the GLS holds its value better than almost any other vehicle in its class due to its high demand as a status symbol and family car. You can expect a steady depreciation of roughly 12-15% annually at this stage of the vehicle's life, which is standard for the premium SUV segment in this region.

Performance & Capability

The 375 horsepower generated by the turbocharged inline-six ensures this massive SUV can sprint from 0-100 km/h in just under 6 seconds, providing plenty of power for confident highway overtaking. The 4MATIC all-wheel-drive system is constantly active, offering superb traction during the occasional heavy rainstorms or when traversing gravel and light sand on the way to a desert campsite. With a ground clearance of approximately 200mm, it handles speed bumps and uneven terrain with ease. The engine is paired with a 9G-TRONIC automatic transmission that keeps revs low at 120 km/h, making it an exceptionally quiet and refined cruiser for cross-border trips between GCC nations. Even when navigating city streets, the steering is surprisingly light, making this large SUV feel much smaller and more maneuverable than it appears.

Comfort & Cabin

The cabin is a genuine 7-seater, featuring electric adjustment for all three rows to ensure every passenger can find their ideal position. The GCC-specific air conditioning system is exceptionally powerful, with dedicated vents for the second and third rows to ensure quick cooling even after the car has been parked in the sun. Multi-zone climate control allows the driver and passengers to have personalized temperature settings, which is essential for family harmony during the long summer months. The seats are upholstered in premium materials that have been designed to resist the wear of high-mileage use and the intensity of UV exposure. Advanced sound insulation ensures that road noise from wide highway tires is kept to an absolute minimum, allowing for clear conversation or enjoyment of the Burmester audio system at any speed.

Safety

Safety is a hallmark of the GLS, which carries a 5-Star NCAP rating and a suite of sensors designed for high-speed environments. Standard features on this trim include Active Brake Assist, Blind Spot Assist, and Lane Keeping Assist, which are particularly valuable on the multi-lane highways of the UAE where traffic speeds can vary significantly. The PRE-SAFE system can anticipate collisions and take protective measures, such as tightening seatbelts and closing windows, in a split second. Adaptive cruise control makes long-distance driving across the desert significantly less fatiguing by maintaining a safe distance from the vehicle ahead. Additionally, the 360-degree camera system is vital for parking and maneuvering this large SUV in tight urban spaces, providing a bird's-eye view that eliminates blind spots.

The bottom line

This GCC-spec GLS450 is the ideal choice for a large family that prioritizes Mercedes-Benz luxury and safety but wants a more accessible price point than a low-mileage example. Its history of highway driving and formal regional specification make it a reliable and savvy purchase for anyone needing a high-status seven-seater in the UAE.
