The Classic Car Club of America defines a CCCA Classic or is as a fine or distinctive automobile, either American or foreign built, produced between 1925 and 1948. Generally, a Classic was high-priced when new and was built in limited quantities. Other factors, including engine displacement, custom coachwork and luxury accessories, such as power brakes, power clutch, and "one-shot" or automatic lubrication systems, help determine whether a car is considered to be a Classic.
Any member may petition for a vehicle to join the list. Such applications are carefully scrutinized and rarely is a new vehicle type admitted.
This rather exclusive definition of a classic car is not universally followed, however, and this is acknowledged by the CCCA: while it still maintains the true definition of "classic car" is its, it generally uses terms such as CCCA Classic or the trademarked Full Classic to avoid confusion.
United States legal definition
Legally, most states have time-based rules for the definition of "classic" for purposes such as antique vehicle registration; for example, Pennsylvania defines it as "A motor vehicle, but not a reproduction thereof, manufactured at least 15 years prior to the current year which has been maintained in or restored to a condition which is substantially in conformity with manufacturer specifications and appearance."
