Driving Dynamics and Ride Comfort
The GL-Class is engineered to deliver a refined and comfortable driving experience, making long journeys a pleasure. The standard AIRMATIC air suspension system, particularly on higher trims, sets a benchmark for ride quality in its class.
On the Road
The GL-Class offers a serene and composed ride, adeptly smoothing out road imperfections. Its substantial weight and long wheelbase contribute to excellent stability, especially at highway speeds. While it’s a large SUV, Mercedes-Benz has tuned the steering to feel reasonably responsive, though it prioritizes comfort over sporty feedback.

Quiet Cabin: Excellent sound deadening ensures a tranquil interior environment, allowing for easy conversations even at higher speeds.
Stable Handling: The standard 4MATIC all-wheel drive system provides confident grip and stability in diverse driving conditions.
Towing and Capability
As a large, robust SUV, the GL-Class is well-equipped for towing and light off-road excursions, though it’s primarily designed for paved surfaces.
Towing Capacity: Typically rated to tow up to 7,500 pounds, making it suitable for boats, trailers, or campers.
Off-Road: While not a dedicated off-roader, its standard AWD system and good ground clearance (especially with AIRMATIC) offer capability in snowy conditions or on unpaved roads.
Practicality: Space, Seating, and Cargo
The defining characteristic for many buyers is the GL-Class’s impressive practicality. Its three-row seating configuration and generous cargo capacity make it an ideal choice for larger families or those who frequently haul gear.
Seating Arrangement
The GL-Class offers comfortable seating for up to seven passengers.
First Row: Spacious and supportive, with ample adjustability.
Second Row: Offers good legroom and headroom. It can seat three abreast comfortably, and many models feature sliding second-row seats for easier third-row access or to optimize legroom.
Third Row: This is where the GL-Class shines. It offers a usable third row with decent legroom for children and even adults on shorter trips, far better than many compact or mid-size SUVs. The power-folding feature makes it easy to reconfigure the cabin.
Cargo Space
The flexibility of the GL-Class is evident in its cargo hauling abilities.
Behind Third Row: Around 10.3 cubic feet. Enough for groceries or a few duffel bags.
Behind Second Row: Around 38.2 cubic feet. Sufficient for luggage for a family trip.
Behind First Row: A cavernous 72.4 cubic feet. This allows for carrying large items, furniture, or significant gear.
Reliability and Maintenance Considerations
Like any luxury vehicle, the 2015 GL-Class will require diligent maintenance to ensure its longevity and optimal performance. While generally well-built, some common areas warrant attention for potential buyers.
Common Issues to Watch For
While the 2015 model year is part of a generation that received some refinements, a few points are worth noting:
Adaptive Air Suspension (AIRMATIC): Air springs can develop leaks over time, leading to a sagging ride height or compressor issues. Symptoms include uneven vehicle stance, warning lights, or a noisy compressor. Repair can be costly; checking for leaks and proper operation during a test drive is crucial. The National Highway Traffic Safety Administration (NHTSA) website is a great resource for checking any recalls or safety concerns related to specific vehicle systems.
Electrical Gremlins: Some owners have reported random electrical issues, such as malfunctioning sensors, infotainment glitches, or power window problems. These can sometimes be linked to software updates or specific module failures.
Transmission: While generally robust, ensuring smooth shifting and checking for any clunks or hesitations during the test drive is wise. Regular fluid changes are essential.
Engine Mounts: For higher mileage vehicles, worn engine mounts can lead to increased vibration in the cabin.
Maintenance Costs
Expect maintenance costs for a Mercedes-Benz to be higher than for a non-luxury brand. This includes more expensive parts, specialized fluids, and often dealership or specialist mechanic labor rates.
Routine Service: Oil changes, filter replacements, brake service, and tire rotations will be standard.
Major Services: Scheduled maintenance at higher mileage intervals can be significant.
Tires: Luxury SUVs often use premium tires, which can be an ongoing expense.

Buying Guide: What to Look for When Purchasing a 2015 GL-Class
When you’re ready to buy, a thorough inspection and careful consideration of the vehicle’s history are paramount.
1. Vehicle History Report (CarFax/AutoCheck)
Always start with a comprehensive vehicle history report. Look for:
Accident History: Significant body damage or frame repair can be red flags.
Ownership Records: Multiple owners in a short period might indicate issues.
Service Records: A consistent maintenance history is a strong positive sign. Look for evidence of regular oil changes, transmission fluid flushes, and any proactive repairs.
2. Exterior Inspection
Body Panels: Check for dents, scratches, misaligned panels (indicating potential accident repair), and rust, especially around wheel wells and door sills.
* Tires: Inspect tire wear for evenness. Uneven wear can point to alignment or suspension problems. Check the tire brand and age – good quality tires are a plus
