Trying to find Organization that races STOCK cars!

Back years ago I was heavily into NASCAR but when they stopped running STOCK cars and began running race cars I quit watching.  Well, got a new girlfriend and she is a NASCAR nut so I have tried to watch it again.  Well, it's ok, if you like watching hybrid race cars.  But personally if I want to watch race cars, I will watch the Indy cars or AA dragsters.  So I am trying to find an organization that races actual stock cars like one would be able to buy from a dealership.  I thought I would try here on this forum in hopes that someone might know where I can look...
