Yes, I think the red window stickers were the Ford Shelby's but I have also seen the GT500 using blue, green, and red so sometimes I wonder if it always was a rule because other vehicles used red usually Ford Performance vehicle related only though just not all of them.
Per email Ford Performance have said a Mach 1 is a Ford Performance vehicle, I emailed them again about the window sticker color since I cannot find their answer anymore where they said it did not matter.
Yes, lol. When I first bought it I had so many encounters with people I was thinking about making a nooklet to hand out. Mine is still the only one around here.
