The car has A3 Golf headlights, looks like they are "smoked". It has a badge less Golf grille, Probably JOM or Bonrath, and it has a "bad boy look" hood extension, I think Mattig makes one like that.
The "Euro Look" on the A3 Jetta usually consists of getting a European GTi front lip, side door moldings, fender flairs and splashguards, badges and a licence plate holder.
I haven’t seen as many A3 Jettas with European bumpers as I have A4. Probably easier to just "smoke" the blinkers and call it the day.
Here you can see a European spec. Jetta. Has a strange grille/lights combo though.
The most useful modifications though, are to get a pair of European headlights, as the US DOT specs once suck.
