With the incredible miniscule tolerances, it looks to be long odds, regardless. Also, presently, there is no market (ARCA etc. etc.) for this car. When they're done......they're done.
From what I understand, the chassis is sold as a kit which the teams have to assemble. The kits cost $250,000 a piece. According to Rick Hendrick, between the cost of the kit, his parts, and R&D time each car cost close to $500,000 a piece. The body is added on by the teams. Then add in the $22,500 certification fee at the R&D Center.
It's my understanding that ARCA has approved the purchase of the COT but won't be using them until the current stock of old Cup and Busch Series cars is used up. They recently approved their teams buying the old Busch Series cars since they're about ready to flood the market at the end of the NASCAR season for pennies on the dollar.
