Summary

This five-year-old flagship SUV presents a compelling balance of mileage and utility for the GCC market, having covered just over 16,000 km per year, which is well below the regional average. The grey exterior is an ideal choice for the UAE and wider Gulf, as it masks desert dust significantly better than darker tones while maintaining a professional executive presence. As the largest SUV in the Mercedes-Benz stable, it offers a genuine seven-seat experience that is often cross-shopped with the BMW X7 and Range Rover. For the local buyer, this powertrain provides the smooth refinement required for long Abu Dhabi-Dubai highway runs without the higher fuel overhead of the V8 variants. The inclusion of standard 4MATIC all-wheel drive ensures stability during weekend trips through gravel tracks or occasional rainy days in the Northern Emirates.

This Car vs Other 2021 GLS450s

With 81,049 km on the clock, this vehicle sits comfortably below the typical GCC annual average of 20,000 to 25,000 km, representing a well-preserved mechanical life. The grey finish is one of the most resilient colors for local resale, offering excellent thermal properties in the summer heat compared to black. While being an American spec, it offers the same high-output 367 hp engine found in local models, making it a high-value alternative for buyers who prioritize features over regional sourcing.

4MATIC vs Lower Trims

The GLS 450 serves as the benchmark in the lineup, providing standard features that are often optional on smaller SUVs like the GLE, including the AIRMATIC air suspension and 360-degree camera system. This specific trim includes a mild-hybrid system that adds 21 hp of EQ Boost, smoothing out stop-start traffic in cities like Riyadh or Dubai. Unlike base-trim competitors, the GLS includes power-folding second and third-row seats as standard, allowing for effortless cargo management.

GLS450 vs Segment Rivals

The GLS 450 is frequently compared to the BMW X7 and Lexus LX570, leading the segment in ride comfort thanks to its sophisticated air suspension tuning. It offers a more spacious third row than the Audi Q7, making it a superior choice for families who need to transport adults in all seven positions. Its towing capacity of 3,500 kg is competitive with many body-on-frame rivals while maintaining the superior handling and refinement of a monocoque chassis.

Running Costs & Resale

Real-world fuel consumption for this 3.0L inline-six averages approximately 10.1 L/100km, which is efficient for a vehicle of this size during highway cruising. Service intervals for Mercedes-Benz in the GCC are typically every 15,000 km or 12 months, and the extensive authorized service network across the UAE and Saudi Arabia ensures easy maintenance access. While European luxury SUVs depreciate faster than Japanese counterparts, the GLS maintains a strong following in the secondary market due to its 'S-Class of SUVs' status.

Performance & Capability

This SUV delivers a verified 0-100 km/h time of 6.2 seconds, providing more than enough punch for safe highway overtaking at speed. The 4MATIC all-wheel-drive system works in tandem with the air suspension to provide 200 mm of ground clearance, which is ideal for navigating sandy beach access points or mountain roads in Ras Al Khaimah. The 9G-TRONIC automatic transmission is specifically tuned for smoothness, ensuring that long-distance drives between emirates are exceptionally quiet.

Comfort & Cabin

Inside, you will find a genuine seven-seat layout with dedicated climate vents for every row, a critical feature for maintaining comfort during 45-degree summers. The MBUX infotainment system with dual 12.3-inch displays provides intuitive navigation for exploring new developments across the GCC. Large windows and a command driving position help reduce fatigue on long hauls, while the boot space expands to a massive 2,400 litres with all rear seats folded.

Safety

This GLS comes equipped with a comprehensive suite of safety tech including Blind Spot Monitoring and Active Brake Assist, which are vital for fast-paced highway environments. The 360-degree camera system is a standard luxury that makes parking this 5.2-meter vehicle in city malls effortless. Additionally, the multiple-airbag system and high-strength chassis provide top-tier protection for all seven passengers.

The bottom line

This 2021 GLS450 is a smart acquisition for a family seeking flagship Mercedes-Benz luxury without the six-figure price tag of a new model. With its sensible mileage and GCC-friendly grey color, it represents one of the most balanced opportunities currently available in the pre-owned market.
