2015 Mercedes-Benz GL-Class Overview

Is the 2015 Mercedes-Benz GL-Class a Good Used SUV?

The 2015 GL-Class is a good SUV with a luxurious interior, roomy seats, and loads of features. The performance is great too; there’s plenty of engine power, confident handling, and top-tier fuel economy. However, the GL-Class gets lower total cost of ownership and reliability scores than many rivals, so you may spend more on maintenance and running costs than you would with another luxury large SUV.

Used 2015 Mercedes-Benz GL-Class Performance and Interior

The GL-Class is equipped with a range of engines, starting with the base turbodiesel V6 in GL350 BlueTEC models. The top-of-the-line GL63 AMG has a twin-turbocharged V8. You can expect generous power with any of the engines in the range, but the base engine might just be the best. Not only does it have plenty of grunt, but it gets exceptional fuel economy for a luxury large SUV: 19 mpg in the city and 26 mpg on the highway. Despite its considerable size, the GL-Class stays composed through turns with little body roll. The ride is cloudlike even over rough roads. All-wheel drive is standard, and the GL-Class can handle some light off-roading when properly equipped.

Like most vehicles manufactured by Mercedes-Benz, the GL-Class has one of the most elegant and luxurious cabins in the class. All surfaces are covered in top-quality materials. The seats in all three rows are supportive and comfortable, even on long drives. The third row has enough space for adults on short trips, but otherwise they're better suited for children. The GL-Class has full sets of LATCH child-seat connectors on each of the second-row outboard and third-row seats. The second-row middle seat has an additional upper tether anchor.

The GL-Class is packed with interior features, and all models come with dual-zone automatic climate control, a sunroof, and a COMAND infotainment system with a 7-inch display screen, Bluetooth, and mbrace smartphone integration. The infotainment system is controlled with a console-mounted knob. For the most part, the system is easy to use, however some features require digging through menus. The physical controls on the center stack are intuitively arranged.

Should I Consider Another Used GL-Class?

The GL-Class was fully redesigned for the 2013 model year. It saw few significant changes for the 2014 and 2015 model years, aside from a new V6 and an engine stop-start system for 2015. Shopping for an older model could save you some money.

Which Used Mercedes-Benz GL-Class Is Right for Me?

You can't go wrong with the base GL350. Not only does it have the most fuel-efficient engine in the lineup, but it has plenty of features to keep you and your passengers happy. If you want more luxury or high-tech features, step up to the GL550, which is available with massaging seats, heated cup holders, and advanced safety systems, as well as a larger engine.

Mercedes-Benz covers some used models with a certified pre-owned program. Mercedes-Benz certified pre-owned vehicles come with the balance of the original four-year/50,000-mile new-car warranty, plus an additional one-year/unlimited-mileage warranty. If the new-car warranty is expired, you’ll just receive the one-year/unlimited-mileage warranty. Every Mercedes-Benz CPO vehicle must pass a 164-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Mercedes-Benz warranty page carefully.

2015 Mercedes-Benz GL-Class and Other SUVs to Consider

Which Is Better: 2015 Mercedes-Benz GL-Class or 2015 Audi Q7?

The 3-row Audi Q7 can't compete with the GL-Class. The smaller Q7 has less cargo room than the GL-Class, and its third-row seats are too cramped for kids. There are significantly fewer features available in the Q7, too. While the available engines are satisfactory, the handling is not. The Q7 feels clumsy around corners. The Audi earns a lower reliability rating than the GL-Class, as well.

Which Is Better: 2015 Mercedes-Benz GL-Class or 2015 Toyota Land Cruiser?

When shopping for a large luxury SUV, you may not think of the Toyota Land Cruiser. The Land Cruiser is an excellent option for tackling off-road trails while riding in comfort, and its high reliability rating is appealing. However, if you just want a luxurious family hauler, stick with the GL-Class, which has more third-row space, more high-end features, and a more premium cabin. The GL-Class also beats the Land Cruiser's cargo capacity and fuel economy.

Which Is Better: 2015 Mercedes-Benz GL-Class or 2015 Land Rover Range Rover?

If you don't need a third row of seats, the Land Rover Range Rover is an appealing alternative to the GL-Class. There are very few things the Range Rover doesn't excel at. However, we have to recommend the GL-Class; the Range Rover's low reliability rating and bottom-of-the-class total cost of ownership score means it may cost you more time and more money in repairs.
