Bring a Trailer Auctions are the best way to discover, discuss, and buy classic, collector, and enthusiast vehicles. We curate vehicles submitted by our users and craft transparent auction listings that present the vehicles as they are—without superlatives or dubious used-car-lot language. BaT’s knowledgeable community of more than 900,000 users and over 400,000 registered bidders help vet each listing so potential buyers can bid with confidence. The BaT app now makes it easy to browse and bid on vehicles anywhere, anytime–with streamlined vehicle submission functionality coming soon for sellers. DISCOVER AND BROWSE Find out what’s trending, see what’s ending soon, and watch the latest bids roll in on the Discover page. Know what you’re looking for? Search and filter in the Auctions tab to narrow down hundreds of listings. VARIETY OF VEHICLES BaT’s curation mirrors our eclectic taste: off-roaders are mixed with track cars, domestic makes with foreign brands, motorcycles with vintage RVs, parts with projects. We even auction re-creations, kit cars, boats, and automobilia! COMMENT THREADS We’re known for our knowledgeable and active community of enthusiasts. Easily tag other users in the app to keep the conversation going. TRANSPARENT BIDDING Place bids quickly and easily, with no surprise fees. The BaT buyer fee is 5% of the final bid price on top of the winning bid, with a minimum of $250 and a maximum of $7,500. Any additional dealer fees required by the seller will be clearly stated in the listing when applicable. SNIPING PROTECTION Each time a bid is placed at the end of an auction, the clock is extended by two minutes–giving everyone a fair chance to place their maximum bid. CUSTOM ALERTS AND NOTIFICATIONS Push notifications and the Activity Feed keep you up to date on your favorite topics, so you can stay on top of the action in real time. We can let you know when a seller adds more photos to a listing, when your favorite models go live, and when you’ve been outbid, among other things. Update settings for these events, as well as emails and sounds for bids and comments, in the More tab. NEW ENDING SOON EXPERIENCE Now you can keep an eye on multiple auctions simultaneously as they count down in the final minutes. In the new Ending Soon section, watch the comments and bids roll in for all auctions ending in the next 24 hours. EXPLORE RESULTS WITH INTERACTIVE CHARTS See the big picture or focus on what matters to you. Easily find results by adjusting the bid amount, timeframe, or vehicle year, or by making a selection right on a results chart. WATCHLIST The watchlist is home base for all of your favorite auctions, makes, models, categories, eras, and origins–just hit the bell or star to save items. We’ll even let you know when you’ve been outbid on a watched auction so you can quickly place another bid!
