The CCCA is considered to have invented the term classic car, which was coined to describe the vehicles covered by the Club's interest. While the term is nowadays used to describe any interesting old vehicle, many in the US consider it only properly used to describe vehicles considered eligible for the CCCA. This may be considered analogously to the correct usage of 'Classical music' to mean only from a specific historical period, even though many people use the term to mean any orchestral work.
