There are two types of Internet auctions: business-to-person or person-to-person. Sellers of business-to-person auction sites have physical control of the merchandise being offered and accept payment for the goods. In person-to-person auctions, individual sellers or small businesses offer their items for auction directly to consumers. Generally, the seller, not the site, has physical possession of the merchandise. After the auction closes, the seller is responsible for dealing directly with the highest bidder to arrange for payment and delivery.
Do your research. Check Kelly Blue Book for the proper price for the vehicle, including its mileage and apparent condition. Always downgrade the condition by one ranking for government auctions. Also, do some smart used-car research, such as checking Consumer Reports for reliability and the frequencies of particular repairs, and checking our road test information if it's a recent model vehicle.
