I think alot of the slow down in the stock /superstock area is just a microcosm of what has happened to the entire automobile industry and the American car culture. I am in my mid 30's and alot of the peope I know drive Honda's, Toyotas, Nissans. Those were the first cars they drove (because they were cheaper/more dependable??) and thus that is what they have purchased for themselves as time has passed and they have moved up in income brackets. They may have traded their Corola for a Highlander, but it is still a Toyota.
In past generations, this happened to be the way Chevrolet, Ford, and Mopar sold cars. The brand loyalty that the big three laid back and was dependent upon to sell cars has long since gone by the wayside.

I don't think alot of young adults that have the $$$ to compete in Stock/SS/Mod have the background to become interested in those classes. They can't identify with a Camaro, Dart, Mustang, Chevelle unless they were introduced to those cars at some earlier point in their life.
