Based on the photos so far there are two ways that Ford MIGHT cheapen the Fiesta for the US.
1 is using wheels from the current Focus. I see that in almost every spy photo.
2 is removing the in-dash screen and buttons and replacing it with a simple slide-out stereo. Like this:
XceedSpeed - View Single Post - ford fiesta
This is the only time I've ever seen this interior treatment. Even the Fiesta van in Europe has the screen and buttons. This was photographed in the US so that means it must be under consideration.
Now, I'm not all that attracted to the big screen in the dash but this is a rather crude way to get rid of it. I hope they dump this idea.
