I'll only gain interest in the change if they start running Challengers, Camaros, and Mustangs, and not offer essentially what they are using now with a shell that is supposed to look like a Challenger, Camaro, or Mustang. The Challenger should use one of the Hemis that will be offered in, the Camaro should feature whatever LS engine that is being used in the production model, and the Mustang should use a Modular engine that they are using in the production model without a supercharger. This way it is more realistic like the way it used to be. I will also gain interest if the Toyota model that they sponsor is actually the production car and not just an engine that is only used in NASCAR and not in any of their production models. If they can't offer a model that can compete then they can get out of it.
