Definitely old gt500 wheels,looked it up.Do not think it is the production finish though. Too many flecks missing, and it has blackish Grey paint. Could be the carbon fiber wheels.
In the 6g website, there was/is a forum where you share the picture of the s550 that convinced you to like it or get one. I thought I should start one.
Here are the ones that made me love it.
I thought that it looked better at first, but I like the GT better. I would like the ecoboost to have the gloss black grille surround, not the brown/grey plastic.
