Auto auctions are a method of selling new, and most often, used vehicles based on auction system. Auto auctions can be found in most nations, but are often unknown to most people. This is, such as in the case of the United States, because this a protected source for used car dealers. Since 1948, the National Auto Auction Association (NAAA) has been helping colleagues in the remarketing community. The NAAA consists of over 300 domestic and international auctions. This organization demands that its members meet certain requirements and operate secure, neutral auction settings. In other countries, such as Japan, auto auctions are well known and used (indirectly) by most people.
