If you are a Guest Member, you will need to upgrade your account (instruction) to a paid membership to gain access to the Live Auction.
When you submit a maximum bid during the preliminary phase, and your bid is not exceeded, you will be prompted to increase your buying power to be eligible to bid in the live auction.
Once you place a bid, that bid is binding and cannot be canceled or retracted. If you win the auction you will be responsible for buying the vehicle at your bid price plus any applicable auction fees.
