A proxy bid is a pre-set maximum amount a buyer is willing to pay for a vehicle at auction. The system automatically places incremental bids on the buyer's behalf, only going as high as the proxy limit. If another bidder exceeds the proxy, the system stops bidding automatically.
Proxy bidding is especially valuable in online auctions where a dealer cannot monitor every vehicle in real time. It removes emotion from the bidding process, enforces discipline around maximum acquisition costs, and allows dealers to compete across many auctions simultaneously without being actively present for each one.
