About This 2020 Mercedes-Benz GLS 450

The 2020 GLS was a landmark year for Mercedes-Benz. This generation represented a complete redesign of the flagship SUV, growing larger, more luxurious, and significantly more technologically advanced than its predecessor. At 93,310 miles, this GLS 450 has been driven but is well within the range that a properly maintained Mercedes-Benz can cover without hesitation — these vehicles are built to exceed 200,000 miles with routine service. For a buyer who wants the full flagship-SUV experience without the steep depreciation of a brand-new unit, this is a smart entry point into the GLS lineup.

2020 Mercedes-Benz GLS 450 Performance and Engine

Under the hood sits Mercedes-Benz's 3.0-liter turbocharged inline-six engine — an architectural upgrade over the V6 it replaced. This engine produces 362 horsepower and 369 lb-ft of torque, figures that feel genuinely effortless when merging onto the 710 Freeway or accelerating out of South Gate toward the 105. Power is routed through Mercedes-Benz's smooth and responsive 9G-TRONIC nine-speed automatic transmission, which keeps the engine in its powerband whether you're cruising at highway speeds or navigating tighter urban streets. The 4MATIC all-wheel-drive system adds year-round confidence, whether you're driving through a rare Los Angeles rainstorm or heading out to Big Bear on a winter weekend.

Mercedes-Benz GLS 450 Features and Interior

Comfort and Space

The 2020 GLS 450 is one of the most spacious luxury SUVs in the segment, offering three rows of seating with genuine comfort even in the third row — something competitors often struggle to deliver. The cabin is wrapped in premium materials with available leather upholstery, real wood trim, and Mercedes-Benz's signature attention to material quality throughout every surface.

Technology and Connectivity

This generation introduced Mercedes-Benz's MBUX (Mercedes-Benz User Experience) infotainment system, which includes a large touchscreen display, voice control with natural-language recognition, Apple CarPlay and Android Auto compatibility, and a sophisticated navigation system. The dual 12.3-inch displays — combining the instrument cluster and infotainment screen — give the GLS 450 a cockpit feel that remains modern even today. Expect features like a panoramic sunroof, ambient interior lighting, a Burmester surround sound system, and multiple USB charging ports throughout the cabin.

Safety Technology

The 2020 GLS 450 came equipped with Mercedes-Benz's comprehensive suite of driver assistance systems, including active lane-keeping assist, adaptive cruise control with stop-and-go functionality, automatic emergency braking, blind-spot monitoring, and a 360-degree camera system — all of which remain exceptionally useful for navigating the dense traffic corridors of the greater Los Angeles area.

Mercedes-Benz GLS 450 Reliability and Ownership

The 2020 redesign addressed many of the reliability concerns that some owners had with earlier GLS generations. The new 3.0-liter turbocharged six-cylinder is a strong unit with a solid track record. Mercedes-Benz recommends service intervals at approximately every 10,000 miles, and buyers should request service records to confirm the vehicle has been maintained on schedule. Common items to verify at this mileage include spark plugs, air filters, and brake condition — all routine items for a vehicle of this age and use. Overall, the 2020 GLS 450 has earned a strong reputation among owners for its powertrain durability and long-term build quality when properly cared for.
