Took delivery and here are some quick notes.
Since I need to take it easy the first 1,500 km, I was stuck in comfort mode and will be for quite some time.
The moment you drive off, you get to feel the weight of the steering wheel and the MCT transmission mechanical noise upto 40 km/h while it up-shifts vs standard 9G on the E450, which was super smooth as butter which I kind of miss

or maybe because I'm still going through the break-in procedure with the engine/transmission/brakes/tires etc.. and everything kind of feels too tight ?
The brakes bite a lot harder than my E450 with a slight tap (Steels). I'm glad I didn't bother choosing Carbon Ceramics.
Cruising on the highway with 4 cylinders deactivated, I was seeing 120 km/h come up much faster than my E450 with 6 cylinders and I was hardly even trying to accelerate reminding myself it's still a brand new car
Big changes with infotainment system + 360 Cam which is awesome, I'm still in learning mode, trying to memorize all the buttons/settings and displays.
All USB ports are replaced with USB-C, the adapters included helped me connect my USB/MP3.
Seats are a bit stiff, but I'm still going through the adjusting period and keep on lowering them more and more, which felt tight and nice in the corners.
The car is super quite in comfort mode and you can fly under the radar, as if it were a standard E-Class. I haven't tried to activate the exhaust button yet. Saving the best for last 1,500km+
