I don't know, a 57 Chevy with a mercedes engine would be pretty sweet, as wood a nomad, or hell, a suped up (inside) 59 Cadilac, with classic exterior.
As for 7, I don't see where it was painted "pink" (aside from the Pink Peckers & VF-11 MAXL Kai). The guitar's were merely alternate control schemes (they weren't played in order to fly), the color's on the SF Valkyries were just that,colors. The faces were far from offensive, etc.
