NASCAR, founded in 1948, perhaps is the best-known symbol of stock car racing in the United States. In its early, the organization had a requirement that any car entered be made entirely of parts available to the general public through automobile dealers; hence, the concept of “stock car.” The facing vehicles were so close to those purchased by the average driver and race drivers often would drive to the track in their race car and then use it on the track. Early racing venues were dirt tracks.
