On-site auctions – Sometimes when the stock or assets of a company are simply too vast or too bulky for an auction house to transport to their own premises and store, they will hold an auction within the confines of the bankrupt company itself. Bidders could find themselves bidding for items which are still plugged in, and the great advantage of these auctions taking place on the premises is that they have the opportunity to view the goods as they were being used, and may be able to try them out. Bidders can also avoid the possibility of goods being damaged whilst they are being removed as they can do it or at least supervise the activity.
Internet auctions – With a potential audience of millions the Internet is the most exciting part of the auction world at the moment. Led by sites in the United States but closely followed by UK auction houses, specialist Internet auctions are springing up all over the place, selling everything from antiques and collectibles to holidays, air travel, brand new computers, and household equipment.

Participants in any Treasury auction consist of small investors and institutional investors who submit bids categorized as either competitive or non-competitive tenders. Non-competitive tenders are submitted by smaller investors who are guaranteed to receive bills, but they won’t know what discount rate they will receive until the auction closes. In effect, these investors receive no guarantee on the price or discount received. An investor who submits a non-competitive bid agrees to accept whatever discount rate is decided at the auction, determined by the competitive side of the auction which is handled as a Dutch auction. The minimum non-competitive tender for a Treasury bill is $10,000. The non-competitive closing time for bills is normally 11:00 a.m. Eastern Time on auction day.

Due to the various governmental units that supply the vehicles for auction, there's no single reason for vehicles being brought to auction. Some of the vehicles are confiscated due to the former owner's involvement in drug dealing, smuggling, or fraud, while other vehicles were simply just abandoned.

One reason is if, as mentioned above, a passenger has not declared the item(s) or if they have been declared falsely. Another reason would be if an individual carried with them over 200 grams of tobacco or a very large amount of alcohol.
