Summary

This 2020 GLS450 represents a sophisticated choice for GCC families who require the space of a full-size SUV without sacrificing the prestige and technology of a flagship Mercedes-Benz. With its three-liter turbocharged engine, it provides a smooth balance of power and efficiency that excels on long hauls between emirates. The black exterior is highly sought after in the regional used market, ensuring strong resale demand when it eventually comes time to upgrade. While this is an American spec vehicle, it offers an incredible value proposition for buyers who want high-end German engineering at a more accessible entry point. This model stands out for its serene cabin insulation and advanced suspension, making it one of the most comfortable seven-seaters currently available for highway commuting. The most important consideration for a GCC buyer is the massive interior volume, which provides genuine comfort for all three rows even during the height of the summer heat.

This Car vs Other 2020 GLS450s

While many vehicles in the GCC accumulate lower mileage due to the concentration of urban centers, this example sits at an average usage level for a high-end family SUV typically used for daily commuting and weekend travel. In the local market, high-mileage German SUVs are often better maintained mechanically than low-mileage examples that have spent too much time idling in traffic. The black finish on this car is a primary advantage, as it is one of the top three colors for resale retention across the UAE and Saudi Arabia. Being a 2020 model year, it features the updated MBUX infotainment system which makes it significantly more modern than 2019 or older variants. Buyers will find this particular unit presents a significant saving compared to GCC-spec equivalents while offering the same fundamental drivetrain and prestige. The mileage reflects a car that has been driven regularly, which is often preferable for preventing the seal and gasket issues that can plague stagnant luxury vehicles in extreme heat.

Not specified vs Lower Trims

Choosing the GLS450 over smaller SUV platforms brings a level of standard equipment that rival vehicles usually keep on the options list. This trim includes the sophisticated Burmester surround sound system and the enhanced MBUX interior assistant, which are often expensive add-ons in lower-tier models. You also benefit from the 48-volt EQ Boost system, providing a smoother start-stop experience and improved torque during initial acceleration—a feature not found on older or lower-displacement engines. The cabin is outfitted with higher-grade materials including extended leather surfaces and ambient lighting with 64 color options that create a premium atmosphere for night driving. In the GCC, the multi-zone climate control is a standout feature, allowing the driver, front passenger, and rear rows to set independent temperatures which is vital for family comfort. Additionally, this trim often includes the 360-degree camera system, making parking this large SUV in tight city malls a much simpler task than in base-trim configurations.

GLS450 vs Segment Rivals

The GLS450 is most frequently compared to the BMW X7 and the Lexus LX series, but it carves out its own niche by offering a more car-like, refined ride quality than the body-on-frame rivals. While the Lexus is known for off-road durability, the Mercedes-Benz leads significantly in highway stability and aerodynamic efficiency, which results in a much quieter cabin at speeds of 120 km/h. Compared to the BMW X7, the GLS450 generally offers more usable third-row legroom, making it the better choice for those who actually intend to carry seven adults semi-regularly. The fuel tank capacity is generous, allowing for long-range cruising across the borders into neighboring GCC states without frequent refueling stops. Its air suspension system is also widely considered the benchmark for this segment, soaking up road imperfections better than many American-made luxury competitors. In terms of technology integration, the twin-screen dashboard layout remains more intuitive and visually impressive than the interiors of the Cadillac Escalade or Lincoln Navigator from the same era.

Running Costs & Resale

Owning a GLS450 in the GCC involves a structured maintenance schedule at 15,000 km intervals to keep the turbocharged engine and mild-hybrid system performing optimally in the heat. Fuel consumption is surprisingly reasonable for a vehicle of this size, averaging approximately 10-12 liters per 100km on highway stretches, though this can rise to 15 liters in heavy city traffic. Parts availability is excellent across the UAE with specialized independent workshops and official distributors in every major city from Dubai to Muscat. While American spec cars depreciate slightly faster than GCC spec cars, they offer a much lower initial purchase price, meaning your total capital loss over three years is often comparable to a GCC model. Resale remains strong because the GLS is a high-demand family vehicle that appeals to a wide demographic in the secondary market. Yearly registration and insurance costs are standard for the engine displacement class, and the use of 98-octane fuel is recommended to maintain the engine's long-term health.

Performance & Capability

The heart of this SUV is the 375 horsepower six-cylinder engine, which allows this large vehicle to sprint from 0-100 km/h in roughly six seconds—a feat that is incredibly impressive for its weight. This power is essential for safe overtaking on fast-moving highways like the E11 where traffic moves at high speeds. The 4MATIC All-Wheel Drive system provides exceptional grip, not just for wet roads but for maintaining stability on sandy highway shoulders or gravel tracks leading to desert camps. While it is not a dedicated rock-crawler, the adjustable air suspension allows you to increase ground clearance to clear light obstacles or uneven terrain during weekend outings. The 9-speed automatic transmission is tuned for smoothness, ensuring that gear changes are virtually imperceptible whether you are in stop-start city traffic or cruising at speed. This combination of a powerful inline-six engine and sophisticated electronics makes the GLS450 feel much smaller and more agile from the driver’s seat than its physical dimensions would suggest.

Comfort & Cabin

The interior of the GLS450 is designed to be a sanctuary from the harsh outdoor environment of the GCC. With seven full-sized seats, the second row can be adjusted electrically to provide limousine-like legroom, while the third row is easily accessible even for adults. The air conditioning system is exceptionally powerful, specifically engineered to move huge volumes of air to cool the large cabin quickly after it has been parked in the sun. Standard features often include a panoramic sunroof with high-quality heat-reflective glass to minimize cabin temperature soak. The materials used throughout the cabin, from the soft-touch plastics to the real wood trim, are designed to withstand high UV exposure without fading or cracking. Long-distance comfort is handled by ergonomically designed seats that offer multiple points of adjustment, ensuring that even a four-hour drive to Liwa or Salalah leaves passengers feeling refreshed. The inclusion of multiple USB-C ports throughout all three rows ensures that every family member's devices remain charged during long road trips.

Safety

Safety is a hallmark of the Mercedes-Benz brand, and the 2020 GLS450 comes equipped with a suite of features that provide peace of mind in unpredictable traffic. Standard active safety includes Pre-Safe technology, which prepares the cabin for an impact by tightening seatbelts and closing windows if a collision is detected. Blind Spot Assist is particularly valuable on multi-lane GCC highways where high-speed lane changes are common. The vehicle also features Lane Keeping Assist and Active Brake Assist, which can detect pedestrians or slowing traffic and apply the brakes if the driver fails to react. For nighttime driving on unlit desert roads, the LED Intelligent Light System adjusts the beam pattern to provide maximum visibility without blinding oncoming traffic. The sturdy chassis and comprehensive airbag system, including side curtain airbags for all three rows, have earned this model top safety ratings globally, making it a trusted choice for transporting your most precious cargo.

The bottom line

This 2020 GLS450 is the perfect match for a family looking for flagship luxury and space at a significant discount compared to a new or GCC-spec model. It offers the ideal balance of performance and presence, making it a standout opportunity for any buyer prioritizing cabin tech and passenger comfort in the current market.
