About This 2020 Mercedes-Benz GLS 450

This 2020 GLS 450 4MATIC Sport Utility comes in with 65,422 miles — a very reasonable figure for a vehicle of this caliber and age.

2020 Mercedes-Benz GLS 450 Performance and Engine

Turbocharged Inline-Six Power

Under the hood, the GLS 450 carries Mercedes-Benz's 3.0-liter turbocharged inline-six engine — one of the most celebrated powerplants in the modern luxury segment. This engine produces around 362 horsepower and 369 lb-ft of torque, delivering effortless acceleration whether you're merging onto I-696 or cruising down Mound Road with three rows of passengers on board.
 

9G-TRONIC 9-Speed Automatic Transmission

Paired with Mercedes-Benz's silky 9G-TRONIC 9-speed automatic transmission, every gear change is smooth and nearly imperceptible. The 4MATIC all-wheel drive system ensures confident traction in Michigan winters — from snowy Warren side streets to slick freeway on-ramps — giving you year-round capability without compromise.

Mercedes-Benz GLS 450 Features and Interior

A Cabin Built for First-Class Comfort

The 2020 GLS 450 was redesigned from the ground up, and the interior reflects that ambition. Seating up to seven passengers across three rows, the cabin is spacious enough for family road trips yet refined enough to feel like a private lounge. The GLS 450 trim includes dual 12.3-inch digital displays forming the MBUX infotainment system — one of the most intuitive in the industry — along with voice control, wireless connectivity, and navigation.

Ambient interior lighting, premium leather upholstery, heated and ventilated front seats, a panoramic sunroof, and a Burmester surround sound system combine to create an environment that genuinely separates the Mercedes-Benz experience from the competition. Driver assistance features like adaptive cruise control, active lane keeping assist, blind-spot monitoring, and automatic emergency braking make every commute and long-distance drive more relaxed and secure.

Mercedes-Benz GLS Reliability and Ownership

The 2020 GLS 450 benefits from a complete platform overhaul, and early reliability data has been encouraging. Mercedes-Benz's turbocharged inline-six engine has a strong track record for longevity when maintained with quality oil and regular service intervals. Owners consistently praise the ride quality, cargo versatility, and third-row usability — areas where the GLS genuinely outperforms competitors like the BMW X7 and Cadillac Escalade in real-world feedback.

At 65,422 miles, this GLS is well within a comfortable ownership window. Buyers should budget for routine maintenance items such as brake fluid flushes, air filter service, and tire rotations — standard upkeep for any premium European vehicle. Finding a pre-purchase inspection or reviewing available Carfax history before finalizing your purchase is always a smart move, and Empire Auto Collection is happy to support that process.

Frequently Asked Questions

Is the 2020 Mercedes-Benz GLS 450 a good buy?

Yes — the 2020 GLS 450 is widely considered one of the best full-size luxury SUVs available. The 2020 model year introduced a complete redesign with a new platform, updated MBUX technology, and a more refined turbocharged inline-six engine. It competes directly with the BMW X7 and Lincoln Navigator but offers a distinctly premium driving and interior experience.
 

How many miles is too many on a used GLS 450?

For a well-maintained Mercedes-Benz GLS 450, 65,000 to 100,000 miles is still considered a mid-life range. These vehicles are engineered for longevity, and with proper service history, many GLS owners report smooth, trouble-free driving well past 150,000 miles. The 65,422 miles on this example place it in excellent standing.
 

What does the GLS 450 4MATIC trim include?

The GLS 450 4MATIC is the entry point into the GLS lineup but is far from entry-level in content. It includes the MBUX dual-screen infotainment system, 4MATIC all-wheel drive, a turbocharged inline-six engine, three-row seating for up to seven, driver assistance systems, premium leather, and a panoramic sunroof — among many other standard features.
 

What is the difference between the GLS 450 and GLS 580?

The GLS 450 uses a turbocharged inline-six engine producing around 362 horsepower, while the GLS 580 steps up to a twin-turbocharged V8 with approximately 483 horsepower. For most buyers, the 450 provides more than enough power and offers better fuel economy, making it the more practical and popular choice.
 

Is the GLS 450 good in Michigan winters?

Absolutely. The 4MATIC all-wheel drive system in the GLS 450 is one of Mercedes-Benz's most capable configurations, distributing torque intelligently across all four wheels. Combined with the SUV's ground clearance and stability control systems, the GLS handles Michigan snow and ice with confidence and composure.
