CarGurus Analysis: 2018 Mercedes-Benz GLS
Summary
With 942 currently listed for sale and an average price of $22,349.00, 33.8% of 2018 Mercedes-Benz GLSs for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 Mercedes-Benz GLS 4.8 / 5 stars.
64.9% of 2018 GLS models on CarGurus are accident free.
Why it stands out
The 2018 Mercedes-Benz GLS stands out as a large, luxury three-row SUV that emphasizes comfort, space, and a premium feel. It offers seating for six or seven people and up to 93.8 cubic feet of cargo space, while standard 4Matic all-wheel drive and Airmatic air suspension help give it the kind of composed ride expected from a Mercedes. For 2018, Mercedes-Benz also dropped the GLS350d from the lineup, leaving the GLS450 as the entry point and giving that model a new wheel design.
What makes the 2018 GLS especially distinctive is how much equipment it packed in, even by luxury-SUV standards. The GLS450 came with a 3.0-liter twin-turbo V6 making 362 horsepower and 369 lb-ft of torque, along with heated front seats, MB-Tex upholstery, a sunroof, power-folding third-row seats, an eight-inch touchscreen, and five years of mbrace Connect apps and remote connectivity. The GLS550 added a 4.7-liter twin-turbo V8 with 449 hp and 516 lb-ft of torque, plus features such as soft-close doors, three-zone climate control, front multicontour seats with cooling, navigation with real-time traffic and SiriusXM, Apple CarPlay, Android Auto, and a Harman/Kardon surround sound system. The AMG GLS63 pushed performance further with a hand-built 5.5-liter twin-turbo V8 producing 577 hp and 561 lb-ft of torque, along with AMG Performance all-wheel drive and Active Curve System for flatter cornering.
Even with its strengths, the 2018 GLS is not the most spacious or most modern-feeling option in Mercedes-Benz’s broader lineup, and its third-row access is a known drawback. Still, it appeals to buyers who want a full-size-feeling family SUV with genuine luxury touches, strong power, and a long list of standard and available features. Owners also tend to praise its comfort, performance, and electronic features, which reinforces the GLS’s appeal as a refined, well-equipped three-row SUV.

Unbelievable vehicle. Has every electronic feature you can imagine, plus a few you cant. Driving it is like floating on a magic carpet. Way more power than I need. Most comfortable car Ive ever owned. All in all I couldnt be happier.

The only improvements would be to add a phone charger somewhere other than just in the storeage console.. I would also prefer a roach screen for the navigation system. Other than those additions, I love it!

Thought it would have been more spacious, but the volume was added behind the driver’s seat. The front of the vehicle is the size of a GLE Class, 5 passenger vehicle.
