I like the ones on the Mustang (last photo) a lot. Less angular. But that's JMO. It would be nice to see a side by side comparison. Photochopped wheels on your 2007 GT (or another 2007 with a side shot) and the GT shown above.
Well, if i get them then it will be ones on the Mercedes. I have some 3 piece wheels im getting redone and the ones on the Mercedes are the template we would use.
