Chrysler Prototype 'Cuda 0 miles

Neat part of automotive history, but in my opinion its not a "factory prototype" as the seller is advertising. If its a "tooling proof" model/chassis/part/assembly/etc it should be identical to what the factory tooling produced in 1974 or identical to a 1974 production model minus things here and there that were done to use this as a master model / "tooling proof".
