Restoring, caring for, and maintaining older automobiles is a popular pastime of Americans of all ages. Gatherings, parades, and tours for antique autos sponsored by antique automobile clubs take place throughout the year. These vehicles may be extremely valuable, depending on the model, age, and availability. In many cases, the expenses the owner incurs to restore the vehicle equal to or exceed its actual value. An antique automobile is usually defined as a private passenger-type motor vehicle 45 or more years of age. A classic car must be more than 20-years-old and also be a distinctive type of car. Antique and classic automobiles must be maintained for use in exhibitions, club activities, parades, and other functions of public interest and used only occasionally for other purposes. The vehicle cannot be used primarily to transport passengers or goods. Liability rates are usually much lower than manual automobile liability rates. Physical damage coverage is written on a stated amount basis. The coverages usually provided include liability, comprehensive, and collision.
