It's fun to study the detail differences in the two.
It's obvious that Ford spent a lot of time on getting the design details right. I like those little ridges going up the "C" pillars and the nice detail on the roof. The way they buried the CHMSL in the top of the backlight is very nice, and specing black mufflers instead of raw galvanized really cleans up a wart.
I wonder if the round GT emblem would look good on the 2015. .. If only there were a way to find out....
(Yes, I think it would look good!)
