It looks like they are using a 46-48 Chevy car grill. The Specs page says that it has a 4.6 3 valve Mustang motor in it - seems like an odd choice? It also says that the rear suspension is a 4-link, but in the picture of the exhaust tip you can see a leaf spring and shackle.
It is my understanding they are/were having trouble with GM on the licensing end of things. GM is not wanting to cooperate. Don't know much more than that.
