Brian,
I wasn't born yet either. Between the Mach I and Mach II concept, as well as the 67 Shelby this Chicago Show sure looks impressive.
tesgt350,
I don't mean to come across as a smart alec, but do you know who said the dark moss green GT350 in front of that building was #0003?
JD,
The Goodyear tire memo notes large letters would be used on approximately 230 vehicles, then the molds would be changed to smaller letters.
The car on the elevated platform behind the white Mustang GT fastback is the Mach I concept in the first configuration.
