September 24th, 2026 by

Choosing a luxury SUV is rarely just a matter of transportation. For drivers throughout Edison, Middlesex County, and the New York/New Jersey metro area, it comes down to one question: Is the Mercedes-Benz GLS worth buying?

Whether you’re handling family commutes, planning weekend trips to the Shore, or driving into Manhattan, choosing the right SUV means evaluating a few key factors:

  • Passenger Comfort & Third-Row Usability: Ensuring all three rows provide genuine space rather than cramped occasional seating.
  • Powertrain & Towing Capacity: Having sufficient power and towing performance for boats, campers, or trailers.
  • Ride Quality & Highway Refinement: Advanced suspension engineering capable of isolating rough Northeast roadways.
  • Technology & Active Safety: Modern tech and driver assistance systems that simplify urban and highway driving.

Below is a review of trims, cabin technology, performance, and ownership options to help you determine if the GLS fits your needs. Local shoppers can also explore the full lineup in person at Ray Catena Mercedes-Benz of Edison.

Key Takeaways: 

  • The S-Class of SUVs: The Mercedes-Benz GLS delivers premium sedan refinement and craftsmanship in a three-row design.
  • Tailored Trim Hierarchy: From the everyday balance of the GLS 450 to the V8 strength of the GLS 580 and the performance-focused AMG® GLS 63, each trim serves distinct driving priorities.
  • Purpose-Built Dimensions: The GLS is ideal for buyers needing standard three-row seating and towing capacity; those prioritizing easier suburban mobility may prefer the midsize GLE.
  • Supportive Driver Systems: Mercedes-Benz active safety technologies assist in stop-and-go traffic and tight parking, though they don’t replace attentive driving.
  • Flexible Purchasing Paths: New models and Certified Pre-Owned (CPO) vehicles provide ownership benefits depending on feature preferences and warranty goals.

What Is the Mercedes-Benz GLS?

The Mercedes-Benz GLS is the automaker’s largest and most luxurious SUV. Positioned as the “S-Class of SUVs,” it anchors the brand’s full-size luxury tier, with seating for up to seven passengers across three rows. Built on a unibody platform, it combines the road manners and acoustic quietness of a premier sedan with the elevated driving position, cargo flexibility, and weather confidence expected of a top-of-the-line utility vehicle.

 

2026 GLS Trim Lineup at a Glance

The GLS model range offers tailored performance levels, luxury appointments, and styling packages:

  • GLS 450 4MATIC®: The entry point to the lineup, pairing a turbocharged inline-six with EQ Boost mild-hybrid assistance and luxury features for everyday family driving.
  • GLS 580 4MATIC®: Upgrades to a twin-turbo V8 engine, delivering impressive acceleration and effortless towing for road trips and heavier loads.
  • Mercedes-AMG® GLS 63: Developed by Mercedes-AMG®, featuring a handcrafted AMG® V8, sport-tuned suspension, and distinctive AMG® styling.
  • Mercedes-Maybach GLS 600: The luxury tier positioned at the top of the platform, designed around executive chauffeured comfort with rear reclining lounge seating.

Performance and Ride Comfort

Every GLS comes standard with 4MATIC® all-wheel drive (4MATIC®+ on AMG® models) and a 9-speed transmission. The GLS 450 produces 375 horsepower from its turbocharged 3.0-liter mild-hybrid inline-six, offering smooth power delivery ideal for suburban and highway commutes. Drivers looking for greater reserve power can step up to the GLS 580’s 4.0-liter biturbo V8 generating 510 horsepower, while the AMG® GLS 63 elevates output to 603 horsepower.

Where the GLS truly differentiates itself is how smoothly it drives. Standard AIRMATIC® air suspension continuously adjusts to smooth out road imperfections on the Garden State Parkway or Interstate 287. Available E-ACTIVE BODY CONTROL on select trims scans the road surface, actively leaning into curves and softening bumps to maintain a quiet ride.

Interior, Space, and Technology

The GLS seats up to seven passengers, with optional second-row chairs. Unlike many midsize alternatives with a tight third row, the GLS offers third-row legroom and headroom that work for most adults.

The dashboard is anchored by dual 12.3-inch digital displays running the intuitive Mercedes-Benz User Experience (MBUX) system. Passengers benefit from standard climate control, available heated and ventilated massage seating, and premium sound systems. Power-folding rear seating allows easy configuration of cargo space for golf bags, luggage, or equipment.

Safety and Driver-Assistance Features

Safety remains central to the GLS platform. Key driver-assistance systems include:

  • Active Brake Assist: Helps prevent front collisions with vehicles and pedestrians.
  • Blind Spot Assist: Alerts drivers to vehicles in their blind spot when changing lanes.
  • Active Parking Assist & Surround View: Makes parallel and perpendicular parking easy in congested downtowns.
  • PRESAFE® Systems: Tightens seatbelts and closes windows when sensors detect an imminent collision.
  • ATTENTION ASSIST®: Monitors steering and driving patterns to alert drivers.

Who Is the Mercedes-Benz GLS Really For?

The GLS is specifically engineered for:

  • Growing Families: Drivers needing three-row space without sacrificing high-end craftsmanship or legroom.
  • Boating and Travel Enthusiasts: Drivers requiring a high towing capacity to transport boats or trailers.
  • Corporate & Executive Fleets: Companies looking for an impressive, comfortable client transport vehicle.
  • Performance SUV Enthusiasts: Drivers who want sports car acceleration and an AMG® exhaust in a full-size platform.

New vs. Certified Pre-Owned GLS

When choosing between buying new or Certified Pre-Owned GLS, both paths offer distinct advantages:

  • New Mercedes-Benz GLS Advantages:
    • Protected by the standard 4-Year / 50,000-Mile New Vehicle Limited Warranty.
    • Features the latest technology, driver-assistance updates, and full factory customization options.
  • Certified Pre-Owned (CPO) GLS Advantages:
    • Delivers luxury at a more accessible investment level.
    • Includes remaining original warranty coverage supplemented by an additional 12-Month / Unlimited-Mile CPO Limited Warranty.
    • Every vehicle must pass a rigorous 165+ point inspection by Mercedes-Benz-trained technicians to qualify.
    • Limited to vehicles six model years old or newer with fewer than 75,000 miles. CPO program terms are set by Mercedes-Benz USA and subject to change.

Final Verdict: Is the GLS Worth Buying?

If your priority is a spacious luxury vehicle that isolates harsh roads, comfortably seats adults, and delivers effortless power, the Mercedes-Benz GLS is well worth buying. It’s one of the most refined full-size SUVs available, yet it never feels unmanageable. However, if seven seats and heavy towing are unnecessary, the midsize Mercedes-Benz GLE provides many of the same benefits in a more compact body.
