It would be a hell of alot of fun!!
A better war would be Toyota/ Honda or something similar, not Toyota/ Toyota shoot out. Chevy/Ford have been duking it out ever since Christ was still in the "Manger" (Did I spell that right?)
Don't see it coming to realization it would have to be a local track. I doubt anyone's gonna cart their Supra across the continent just to prove almost nothing. But don't get me wrong I'd love to do it. You'd have to rent the track for a day/days. Then car and driver would have to track legal. So, this would have to be a local war and this would exclude over half the members. Some members share forums and would have to pick sides.
Go ahead flame me, I have my flame suit on, tested and ready!
