Keep Track of your Auction listing, where you'll get notified when someone initially bids on your car, when out bidded by other users and when the Auction expires with / without a winning bidder. Also, 6 hours before any auction expires an email is broadcast to all bidders who bidded on a car item and users who have that car auction in their watchlist notifying them of the status of the Auction and urging users to bid on that Car item.
