"What I'll call "A" is the final Plymouth Road design studio mockup. This is one of two oft-seen mid-'68 photos taken in the AMC styling auditorium and shows the Di-Noced and foiled final full-size mockup. I believe it's a fiberglass model (as was the AMX/2) rather than a wood- armature clay, but the 7- [?] spoke wheels (that never reached production) were custom made in Italy to a design seen in the "final" rendering release (See Main page artwork) and are likely fully weight-bearing castings rather than just Saffalloy or plated plastic for show. Car "A" was a refinement of the AMX/2 competition model unveiled in 1969 (within AMC early in February '69 and publicly at the Chicago show later the same month), and its concept was Teague's with significant fleshing- out by Fred Hudson and Bob Nixon (interesting names, huh?). AMX/3 "A" buck sizing was somewhat changed from AMX/2, it being wider and with certain other proportions minimally-altered perhaps as a result of influences derived from the Ital Design competition entry penned by Giorgio Giugiaro, which was slightly lower [!] and longer than the AMC studio design. Guigiaro's car was Fome-Cor, not fiberglass, probably to minimize construction costs and shipping weight from Italy to Detroit. "A" also usually served as the photographic model for AMX/3 detail and image renderings used both in-house and for various media releases."
