In the United States, an antique car is generally defined as a car over 45 years of age, this being the definition used by the Antique Automobile Club of America. However, the legal definition for the purpose of antique vehicle registration varies widely. The antique car era includes the veteran car era and the brass car era which is from the beginning of the automobile up to the 1930s. 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.
