RE: Challenger Ad
I think he is right about the shrouded car in the link...it's production. Why would they cover up the concept car when they have already driven it around uncovered? That makes NO SENSE! The only reason to hide it is if it is something we have not seen yet. A la - production.
Besides, the door handles are clearly different as well as the inner headlamps. I can't make out much more but that's my untrained eye. The billboard pics are the concept certainly but these "spy pics" I would have to say are the production version.
