Consignee and consignor - as pertaining to auctions, the consignor (also called the seller, and in some contexts the vendor) is the person owning the item to be auctioned or the owner's representative, while the consignee is the auction house. The consignor maintains title until such time that an item is purchased by a bidder and the bidder pays the auction house.
It is important to have realistic expectations when attending a government car auction. While you can find some good bargains, you are not going to find a brand new BMW for $100.00. Government auctions sell both fleet cars and vehicles that have been impounded by government agencies. The conditions of these vehicles can range from great to not running. Set your expectations and budget realistically.
