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.
