NASCAR was formed in 1948, during the post-war era. Because new cars were scarce at the time, the founders were hesitant to use and abuse new race cars in front of fans who were struggling to get around in their old, well-worn cars. Consequently the NASCAR president, Bill France Sr., opted for the less insulting idea of using only 'stock' cars. This meant competing cars had to be those that could be bought from a dealer and driven by typical street drivers, and they could have no major modifications.
