Haulin.ai Rating: 8.7/10 | Best for: Collector car buyers and sellers, enthusiasts, classic vehicle owners | Auction type: Online, curated 7-day auctions
Bring a Trailer was founded by Randy Nonnenberg and Gentry Underwood and has grown from a blog about interesting cars to the most active online auction venue for collector and enthusiast vehicles in the world. In 2020, Hearst Autos (publisher of Car and Driver, Road & Track, and others) acquired BaT, providing the capital and infrastructure for continued growth.
The platform’s name reflects its original ethos — vehicles interesting enough that you’d want to bring them to a car show, a track day, or a meet. Today, that translates to a curated marketplace for classic cars, vintage trucks, modified enthusiast vehicles, rare imports, motorcycles, and specialty items. If you follow classic car shows and the events calendar, you’ll regularly see BaT-purchased vehicles appearing at shows — the community overlap is substantial.

What sets BaT apart is not just the curation but the community. Every listing generates a comment thread where knowledgeable enthusiasts ask detailed questions, flag potential issues, verify specifications, and debate value. For buyers, this is a form of crowd-sourced due diligence unavailable on any other platform. For sellers, it creates an engaged, transparent auction environment that rewards accurate representation.
By early 2026, BaT counted 1.65 million registered users and more than 500,000 verified bidders — a community density that drives competitive bidding and high sell-through rates.
| Fee | Who Pays | Amount |
|---|---|---|
| Buyer fee (cars & trucks) | Buyer | 5% of final price (min $250, max $7,500) |
| Buyer fee (motorcycles, ATVs, parts) | Buyer | 10% of final price (max $4,000) |
| Classic listing | Seller | $99 |
| Plus listing (professional photography) | Seller | $349 |
| White Glove listing | Seller | Custom pricing |
| Seller commission on sale | Seller | None |
| Verified Checkout | Included | In buyer’s 5% fee |
The fee structure is one of BaT’s most seller-friendly features: sellers pay no commission on the sale price. A $100,000 car sells on BaT with the seller paying only the upfront $99–$349 listing fee. The buyer absorbs the 5% fee (capped at $7,500 on vehicles over $150,000).
For buyers, the 5% fee is worth understanding before you bid. On a $50,000 car, you’ll pay $2,500 to BaT plus the $50,000 to the seller — a total of $52,500 before transport.

BaT is the most recognized name in online collector car auctions. Its transaction volume ($1.7B+ in 2025), sell-through rate (81.8%), and community size (1.65M registered users) are unmatched in the enthusiast vehicle space. The Hearst Autos acquisition added institutional backing. Reputation concerns are limited to isolated incidents of vehicle misrepresentation and, in some cases, slow customer service response.
The BaT platform is clean, functional, and well-suited to its audience. The 7-day auction format with anti-sniping extensions, proxy bidding, archived sales history for comparable research, and the comment-section Q&A model all work well together. The Verified Checkout integration (powered by Caramel) adds a layer of transaction infrastructure that the platform previously lacked.
BaT’s fees are clearly published and straightforward. Buyers know exactly what they’ll owe before bidding: 5% of the final price, capped at $7,500. Sellers know their listing cost upfront. There are no hidden charges or per-auction surprises.
BaT’s curated approach means the inventory is consistently interesting, but it also means submission rejection. Not every vehicle qualifies. The platform’s focus on collector and enthusiast vehicles creates a highly targeted inventory — excellent if you’re in the market for something special, limiting if you need something more practical.
BaT facilitates transactions but doesn’t guarantee vehicle condition. The platform curates submissions and specialists write listings, but physical inspection is not performed. Payment for the vehicle (beyond the buyer fee) is handled directly between buyer and seller. Verified Checkout provides some transaction structure, but condition disputes ultimately rest with the buyer’s due diligence. Some users have reported payment delays when using the Caramel-powered checkout for higher-value vehicles.
Best for buyers who: are looking for a classic, collector, or enthusiast vehicle, are comfortable buying remotely with thorough listing review, want the benefit of community vetting through the comment section, and are prepared to arrange shipping after winning.
Best for sellers who: own a vehicle with genuine collector interest, want access to the largest community of motivated enthusiast buyers, and prefer paying a flat listing fee over giving up a percentage of the sale.
Not ideal for: buyers looking for everyday transportation, sellers with common used cars unlikely to meet BaT’s curation standards, or anyone who needs to sell quickly.
Bring a Trailer earns its 8.7/10 as the definitive online platform for collector and enthusiast vehicles. The combination of curated inventory, community-driven transparency, anti-sniping auction mechanics, and the largest pool of verified enthusiast bidders in the market creates an environment that delivers strong results for both buyers and sellers of interesting vehicles.
The main limitations are the 5% buyer fee, the lack of a guarantee on vehicle condition, and the curated-only model that excludes everyday cars. For the right vehicle and the right buyer or seller, BaT is genuinely hard to beat.

Yes. BaT is a well-established platform owned by Hearst Autos with over $1.7 billion in 2025 sales and 1.65 million registered users. However, BaT facilitates transactions — it does not physically inspect vehicles or guarantee their condition. Due diligence remains the buyer’s responsibility.
Buyers pay 5% of the final sale price, with a minimum of $250 and a maximum of $7,500. For motorcycles, ATVs, parts, and certain other categories, the buyer fee is 10% capped at $4,000 (effective June 2025).
Sellers pay a listing fee — $99 for Classic (owner photos), $349 for Plus (professional photography), or custom pricing for White Glove service. There is no commission on the sale price itself.
Verified Checkout is BaT’s digital transaction service powered by Caramel, available on eligible private-party listings in all 50 US states. It’s included in the standard 5% buyer fee and handles paperwork and payment digitally. For vehicles over $75,000, payment is typically split between pickup and title verification.
BaT does not conduct physical inspections. However, you can arrange an independent pre-purchase inspection through a specialist near the seller. Most sellers accommodate this request during the active auction period. The community comment section also provides crowd-sourced condition information.
Buyers are responsible for arranging transport. Haulin.ai specializes in collector vehicle shipping and offers both open and enclosed transport. Get an instant quote at haulin.ai before the auction ends so you know your full cost.
BaT requires sellers to disclose all known issues and the community holds sellers accountable through the comment section. However, BaT does not provide a vehicle condition guarantee. If a vehicle materially differs from its listing, you would need to pursue resolution directly with the seller. This underscores the importance of independent inspection before bidding on significant purchases.
