Oh yeah, that's one thing Mercedes gets right. Every time I close the door and it makes that thunk, I always think that's the proper sound of a solid door closing. Other cheaper cars used to have the window rattling or something that sounded loose. But it's a solid door and I think pretty much all manufacturers try to have that sound. My W211 had the open assist too, the doors pop open a little when unlocking. In their cost cutting, they got rid of that in the W212.
The pano roof is even more enormous, basically the entire roof is glass, don't have to worry about waxing the roof as there's no metal/paint to wax. I don't see keyless go mentioned as a feature, just the keyless entry which is a standard fob, don't see a start button in the pictures. Plus Mercedes does 3 position memory seats for both passenger and driver as standard. I see they had the rear sunshade, but a Mercedes option was the ones in the side windows.
