There were only two "body styles", the hardtop and fastback.
There were only four "models", Coupe, Ghia, Mach 1 and 2+2.
Everything else (Cobra II, King Cobra, Rallye, etc.) was a package available for one or more of the models.
The Ghia is set apart from the coupe by luxury appointments and the Ghia symbols. Some coupes were available with the vinyl top so that in itself does not set it aside from the Ghia.
