This midsize SUV stands out not just for its generous interior but also for the balance of comfort reminiscent of the S-Class luxury sedan, paired with some off-road capability similar to the G-Class.

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.
