How do Auctions work
 

Hey Folks i am in the process of purchasing a new vehicle, and was looking into something in my budget (2-4k) so as of today i have not found anything only junk.. well i was told by a friend of mines that he bought a vehicle in an online auction http://easyexport.us/?a_aid=4bfc2493cf522 so im wondering if anyone has some insights on online auctions.
