One of the only vehicle auctioneers in the United States to offer test-drives to the general public, Interstate Auto Auction has developed two distinct auctioning systems. Potential buyers may choose to attend an Interstate Auto Auction in person on Wednesdays and Saturdays at the company’s location in Salem, New Hampshire. Alternatively, buyers may bid electronically through Interstate Auto Auction’s live online auctions. Working with the online auction service Proxibid, Interstate Auto Auction enables buyers to view cars and participate in auctions via a Web browser. Interstate Auto Auction’s online bidding process allows buyers from diverse geographical locations find vehicles at significantly discounted prices. Buyers are encouraged to review Interstate Auto Auction’s online catalog prior to the auction and then register to make proxy bids. Once a bid is submitted electronically to Interstate Auto Auction, the buyer does not need to take any further steps. If the buyer is outbid, Interstate Auto Auction sends an email message automatically, including a link allowing the buyer to submit another bid if desired. The bidder is also notified automatically if he or she wins the auction. In addition to listing vehicles for sale, Interstate Auto Auction’s online catalog also shows recently sold vehicles, allowing potential buyers to develop cost estimates. Most of the vehicles sold by Interstate Auto Auction sell for less than 50 percent of the listed retail price. Founded in 2002, Interstate Auto Auction has sold tens of thousands of cars since its inception. Interstate Auto Auction also conducts charity auctions on a weekly basis.
