Folks seem to keep forgetting that the Challenger originated in the Chrysler's Pacifica Studios. It was an in-house effort intended to "test the waters", so to speak, for the possibility of customer interest/support in resurrecting the Challenger.

The 'Cuda was a private company's effort in creating something unique. It was not sponsored, encouraged or espoused by Chrysler LLC, and never intended for production runs. It was a "one of a kind" project car - made from a Charger chassis. Hell, the interior was identical to the Chargers'.
Chip Foose could have made a MUCH better modern take on the 'Cuda if he collaborated with Doug Schramm and they actually executed those ideas.
