"I just picked up my 2015 ML350 4Matic last week...I opted for a few extra bells and whistles like leather seating,heat and massage, ambient interior lighting and the premium package.
Now I'm over 6' tall and well over 200lbs and the ML is probably one of the most comfortable and quiet rides I've ever experienced in any smaller SUV I've ever owned. The leather is plush and the seating is very comfortable. The cabin is very spacious for a smaller SUV. I love the fact that I have that extra leg room. The car has good power and shifts seamlessly.
The steering might take some getting used to as it seems loose, but it is very responsive. I can't pretend to be the most technologically inclined, but you have a large 7" LCD, well formatted Navi, and pretty well laid out music controls.
I still need to delve into the user guide (which is also uploaded into the cars on board hard drive). I'm testing the MBrace feature, which from what I understand, offers up conveniences like emergency services collision notification, concierge services and auto map and computer updates just like GM's OnStar.
Well my preliminary impressions of this vehicle are very good to excellent. The only other option that I believe might be worth having is the "off-road" package which includes air suspension and 20" wheels. But then again, this car's 4Matic feature has been great thus far in in-climate weather conditions.
I think it's very good on gas too! (20 mpg City)"
