I have a '06 GT with the Premium option and leather seats. Looking closely at the rear seats, they do not appear to be made of the same material as the front seats. I looked closely at the "diamond" imprints, and they seem quite different. I know on the front seats, the only part that is leather is where you actually sit, as the sides are vinyl. I'm going to detail the interior this weekend, and I want to use the right products. I'm wondering if the rear is all vinyl. Any one know for sure?
