I would like to have the driver's seat to be lower. Wish it goes down lower with up and down feature. The fabric sun screen on the ceiling is not strong and dark enough to block the strong sun. Is there any extra external device cover it more!? The cupholder should be deeper.

Quiet and smooth driving and safe.

I was involved in an accident and the Mercedes proved to be very safe.

The garage door opener is in an awkward place.

It is a classy vehicle with many extras that are nice. It rides extremely well. The mileage is OK, but not great. Some of the access to controls are not user friendly.

The digital interfaces needlessly overlap. The touch pad makes the wheel more difficult to use. Seems like a design problem to me. That the seat position must be done through the interface is a terrible design change. It's impossible to adjust the seat while driving and pay attention to traffic. The control on the seat is much better. Everything doesn't need a computer to adjust. The user manual and digital version is practically useless. Many references to consult the digital version but there is no additional information. E.g. setting the passenger side mirror to lower when backing...even the salesman didn't know how to do it. Found the multistep procedure on a blog post. I have been used to V8 pick up for years. This V6 doesn't do it for me. If had had to buy it again, I should have stayed with the new GL63. My previous vehicle was a 2013 ML63. Vehicle safety, function, and performance are the most important to me.

Safety features are excellent. Provides comfortable ride. Fuel economy is better than expected, however, pick up is less than expected. Electronics are overly complicated - buttons & knobs would be better in many cases. On board manual isn't helpful. There have been several annoying issues with tire pressure sensors requiring service.
