BID4U represents the highest bidder during both the preliminary bidding process and the virtual auction. Simply enter the maximum price you are willing to pay for the lot during preliminary bidding and BID4U will bid on your behalf up to your maximum bid during the live auction. BID4U will only bid one increment over the current bid to maintain your position as the highest bidder. This allows you to purchase a vehicle below your maximum bid if bidding doesn't meet or exceed your maximum bid.
