Carbureted engiens, leaded gasoline and 1960's truck-style rear suspensions have little bearing on anything "stock" that you can buy at a dealership.
I much prefer race series that use cars that really are based (somewhat) on something that I can buy, but no one else seems to think the same way, so you don't see much TV coverage.
The German DTM series and British/Australian Touring Cars are great, IMHO.
I propse a series where cars are driven straight from the dealership to the track, with minimal prep. But that'll never happen outside of an autocross course.
