the most beautiful car in the world is getting an extensive facelift. Wonder why

I wanted to say it, didn't have to though

'Cause they couldn't handle it.
But it's really what Gian said. There's no coincidence that all Sedans look homogenous now, save for the E who looks to be trying its best to do its own thing. IMO it makes the E more praise worthy in design though M-B chasing down market share will do whatever they can to make it easier to swallow/blend in with the masses. Dual headlamps, take out half of the Ponton crease, happier grille, etc.
As an enthusiast of the car and being that the very nature of the car is already homogenous (Midsize Sedan), I just don't want homogenous elements on it to boot, that's not what gets my goat, but of course I am but one mans opinion.
Oddly enough, I'd love more homogenous elements on a car like the CLS, i.e straightforward lines. The CLS's nature and shape make it practically exotic-ish from the get-go, adding "exotic cues" all over it just makes it too much fuzziness. If they matched more simplistic design elements to go with the architecture, I would have loved it. The E however, being a conservatively natured car, is more beneficial of some *TACTFUL* stand-out decorative elements like quad headlamps, a Ponton fender, etc., to give it some balance with spicy elements.
Basically: A Midsize car is supposed to be boring by nature. If you take a boring car, and try and make it look boring, it'll look boring (pretty much all Midsize Sedans nowadays to some measures) yet very friendly to a wide group who wants nothing polarizing. However, if you try and make it look interesting.... you might turn some people off, but you will also give others who seek something to be inspired by, reason to do so.
