I agree, let manufacturers make their own body to match the actual cars on the lot. Would advance performance, handling and gas mileage as the above motto would hold true.
I have no worries about NASCAR too many things to check, test and inspect. All the regulation is a bit like Mafia. Ease up and let manufacturers do what they do best design. Worked for this great country in the 60's, 70's and then regulation came and US cars went flat.
