Alright, I took what you said to mean you were surprised the car was getting Kinetic Design cues at all. Which it is, just with some differences. Sorry if I was an asshat about it.
But the cosmetic changes are unavoidable; even if Ford kept the grille the same the front end probably needs to be a bit longer anyway to conform to crash standards. Just look at the Honda Fit, the whole front end is pushed out on the American model relative to the global car! They kept the fascia the same but elongated the nose, and personally I'd prefer Ford to keep the proportions intact and give the car a different bumper than elongate the whole front end like the Fit and ruin the car's basic profile.
Bitching about the back bumper isn't going to change anything on the Fiesta either, it's just regulations and THOSE cannot be avoided no matter how much you/me/Ford wants it. Write to your congressman or the DOT or whoever is responsible and tell them we need globally unified regulations...THAT would accomplish alot more than just whining about how we're not getting the amazing flawless European car.
PS - The Fiesta will probably be the last Ford to get the Mach 3 grille; the Taurus already has a much more "European" grille (still 3 bars) and I imagine the next Focus will do away with that look altogether. Time will tell but the point is Ford is moving away from the 3-bar look and trying to do it gradually instead of dropping it abruptly, which IMO makes sense. Now if it was something like the Subaru grille from the Tribeca, which was universally derided, Ford might drop it immediately but the Mach 3 grille is generally okay by most people so they've kept it, and since the 3-bar grilled cars have sold well they're just phasing it out more slowly to avoid customer confusion.
