This looks suspiciously like a dealership brochure, and I'm guessing the closeup shots are the production Challenger! That would explain the different grilles, for sure, and I don't think the concept had a flip-top gas cap, did it?... And the duck-tail spoiler... I stopped at my closest dealer yesterday and they didn't have any brochures.

But they still don't want to give away the entire package -- see the little note that says "concept vehicles shown" where they show the whole car?
