Why it stands out
The 2018 Mercedes-Benz GLS is distinguished as the roomiest vehicle in the Mercedes-Benz lineup, seamlessly blending luxury with functionality. This midsize SUV offers three rows of seating for six or seven passengers, making it an excellent choice for family outings. It provides a generous amount of cargo space, reaching up to 94 cubic feet, ensuring ample room for luggage or sports gear. Many owners have praised its powerful performance and the sophisticated technology that enhances the driving experience. However, some feedback indicates that the interior space may feel less ample for larger families, coupled with suggestions for more charging options. The GLS competes robustly against luxury rivals like the Audi Q7 and BMW X7, often appealing to buyers looking for a blend of comfort and a hint of off-road capability.

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.
