An antique car, in the general sense of the term, is an automobile that is an antique. Narrower definitions vary based on how old a car must be to qualify. In the United States, an antique car is generally defined as a car over 25 years of age, this being the definition used by the Antique Automobile Club of America. However, the legal definitions for the purpose of antique vehicle registration vary widely. The antique car era includes the Veteran era, the Brass era, and the Vintage era, which range from the beginning of the automobile up to the 1930s. Later cars are often described as classic cars. In original or originally restored condition antiques are very valuable and are usually either protected and stored or exhibited in car shows but are very rarely driven.
The Veteran car era, Brass car era, and the Vintage car era, are part of the Antique car classification as all automobiles produced prior to World War I are considered to be antiques.
