Personally I see no logical reason why any auto manufacturer would sponsor any of the pro classes. If you go by the old addage of "what wins on Sunday sells on Monday", what is there about any pro car that would drive someone to the respective dealership - there isn't a single stock part on any one of them and they don't resemble anything rolling off the line. And then there's the cost to bankroll these teams. If I were the guy signing the checks, the big checks would be going to guys racing current body styles so there's actually some "brand recognition". And with the money I saved from sponsoring a few big teams I'd be marketing the hell out of the guys running my stuff. Get back to the days of performance clinics, etc..
