In the United States, generally, antique cars are of over 25 years of age, this being the definition used by the Antique Automobile Club of America. However, the legal definitions of antique vehicle registration vary far more widely.
The antique cars are those which were produced in the Veteran era, the Brass era, and the Vintage era, which are spread from the beginning of the automobile up to the 1930s. Later cars that have been produced after 1930 are often described as classic cars.
In original or originally restored condition antique cars are considered to be very valuable. These vehicles are usually either protected and stored or exhibited in car shows but they are seldom driven.
Some people also consider such collectibles to be a form of investment.
