It's a good idea to check your email or phone regularly after the auction. If you're the high bidder, and the seller can't reach you within this time, he or she may contact the next-highest bidder and sell the item to that person. Contact the seller You will receive an email notice at the end of the auction if you are the high bidder. You should try to contact the seller within 3 days. You do not pay eBay.
Some sellers require a small deposit from the high bidder soon after the close of the auction.
Check the item description for payment terms. Most sellers will expect payment in full before they will sign over the title. Be prepared to pay the seller by the method they have specified. If you are not sure, contact the seller. If there is a lien on the vehicle or you will be using a loan to pay, the finance companies involved may have special requirements.
