I'll echo what a few have said here already: pictures don't do it justice, and it has massive presence in person. Saw one last week and it looks powerful in a way not a lot of modern cars do. It's the "walk quietly, carry big stick" approach. It also pulls off the brand's new coupe taillight treatment far better than the bloated C-Class coupe does. The interior is one of the best out there.
That said, it's a modern Merc, and it looks uncomfortably like the ugly CLA in darker shades from up front thanks to that ungainly family pig nose. I'm torn.
