Why it stands out
The 2018 Mercedes-Benz GLS is designed with families in mind and serves as the roomiest vehicle in the Mercedes-Benz lineup. With options for six or seven seats and up to 94 cubic feet of cargo space, it blends luxury with practical design. While not the tallest or longest in its lineup, the GLS combines the comfort associated with the S-Class luxury sedan with a hint of off-road capability reminiscent of the G-Class. It delivers impressive power and sophisticated electronic features, enhancing the overall driving experience. Although some owners noted that the interior might feel tight in certain areas, the GLS is lauded for its premium feel, comfortable ride, and advanced technology.

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.
