I agree. The current one seems very "soft" in terms of presence and popularity. It looks very imbalanced and bland in normal guise, which is weird as the car isn't a technically blandly detailed or proportioned car.... however, somehow, it just comes off as "bland". However, with an AMG Package and when equipped and better yet-modded just right, it definitely shows of how beautiful it can be, and it *can* indeed be beautiful.
The C215 was a massive hit though, I remember how insanely popular and prestigious it was when it came out.... everybody wanted one.... oddly enough, I never fell totally in love with it and found the styling a little off in some areas, preferring the W220 Sedan over it. The first gen CL was also a huge statement and hit.
The key to the first two were huge monolithic designs, IMO. The current one got sculpted and more detailed, that are good things in their own right, but somehow working with the nature and architecture, I feel they may have worked against the car, in comparison to the slab sided first two.
