The National Automobile Dealers Association (NADA), founded in 1917 and commonly referred to as NADA, represents nearly 16,000 U.S. new-car and truck dealerships, both domestic and international, with about 32,000 separate franchises. It is headquartered in McLean, Virginia. The National Automobile Dealers Association was founded in 1917 by a group of dealers determined to lower the luxury tax on automobiles from 5% to 3% by lobbying Congress in Washington, DC. After the success in Washington, the group decided to form a permanent union and represent the nations 15,000 automobile dealers. In July 1917, 130 dealers met in Chicago where they elected George Browne of Milwaukee to be NADAs first president. In 1975, NADA constructed a new corporate headquarters in Tysons Corner, Virginia where they currently reside at 8400 Westpark Drive. NADA exists to provide automotive information and advocacy to three groups. Consumers are served by their NADA Guides which provide information about vehicle pricing for new, used, and classic automobiles in addition to motorcycles, boats, recreational vehicles, and manufactured homes. Related to this, the company regularly issues reports and press releases about the automotive market such as analysis of the hybrid car market.
