You get the money, Dallara will build you one, and GM approves. It will be interesting to see if we have any takers in the coming years. Mazda has said previously they want to sell customer cars but want to get the package to where it needs to be first. Gotta say, if i had to choose between the two, i might side with the dallara on this.....
