I've been crusing the net and found there is growing support for the Charnum. This linkhas some nice after-market items for horrible looking 4 door family car. I hope they have to same kind of support for the Challenger.

if you consider how popular the car will be if it is priced reasonably, and it looks like the concept, every performance company is going to scramble to make as much as they can...i think that the aftermarket will be as big as the market for the mustang, provided a bit of time. also, since they are using a current engine, there will already be engine parts offered.
