Buyers these days expect fog lights in a well-equipped car. This is another Ford marketing blunder.I wish we got the Euro design too. But no... they're not directly swappable. I'm gonna tell you right now that the price is going to be ridiculous to have a Euro bumper imported. You will also need a Euro hood. Both pieces will obviously have to be painted, and some underbody modification might be required for proper fitment... (stuff like the radiator bracket etc.)
Honestly it's way more trouble than it's worth...Maybe Ford will redesign the front end for 2013 or offer a Fiesta ST with that Euro look, but I wouldn't hold my breath.
