Well, the Spartan. Another neoclassic from the 70's, which strangely used a 280Z as it's base. I suppose it's kinda fitting, as the 280Z had kinda morphed into a luxobarge at that point. Why not make it more luxurious and more barge-y.
I'm thinking he's looking at replicating the 1959/1960 El Camino, except instead of having a bed it has a a reeeeally long trunk. Kind of like the SSR.
