The aim of the AACA is the perpetuation of the pioneer days of automobiling by furthering the interest in and preserving of antique automobiles, and the promotion of sportsmanship and of good fellowship among all AACA members. The AACA uses the term "automobile" in a comprehensive sense to include all self-propelled vehicles intended for passenger use (cars, race vehicles, trucks, fire vehicles, motorcycles, powered bicycles, etc.). Similarly, the term includes various power sources, such as gasoline, diesel, steam and electric.
