Everyone to their own taste, I suppose, but those overriders are even uglier -- if that's possible -- than those extended US bumpers!
Gimme standard, all-chrome, Euro bumpers any time, designed as they were meant to be by M-B and not to some petty bureaucrat's specifications.
As for the notion that bumpers had to survive a 5 mph collision ...
The rear bumper on my 116 has a really small wrinkle on each corner. These barely noticeable dings (one has to know they're there in order to spot them) are the only damage sustained when a Daewoo completely demolished itself on one corner and a Hyundai on the other (okay, so those aren't really cars by my definition, but they are allowed on the roads). In both instances I was stationary and the other vehicles were travelling at 50-60 km/h (30-35 mph). I doubt those ugly "5 mph" monstrosities would have fared any better.
Both the offending cars -- each less than a year old -- were written off, and the driver of one was moderately injured when her seatbelt mountings failed, door flung open, and she was ejected onto the roadway.
But hey -- if those overriders float your boat, then go for them.
