Or just never noticed, the first gen Focus has a really weird antenna. I remember on my Mom’s wagon she got one of those smiley face things that people put on their antennae. She had to take it off because when the car got up to speed it would bang in the roof. It was kinda scary the first time it happened.
Apparently the Euro second gen maintained the odd detail. Even on the convertible, which looks especially odd.
However the US second gen moved it to the back, where it belongs.
