A look at Bring a Trailer, a classic car blog from 2007 that became a marketplace, facilitated $1.37B in 2022 sales, and held its 100,000th auction on March 7
Bring a Trailer is where obsessives buy, sell and geek out over classic cars. The company pops open its hood after 100,000 auctions to explain why.
Context & Ripple Effects
Bring a Trailer started in 2007 as a classic-car blog and grew into an auction marketplace with real scale: it reported 100,000 registered bidders and $230M in 2019 sales in earlier coverage of its auction model, and this week's profile lands after it crossed both $1.37B in 2022 sales and its 100,000th auction on March 7 — roughly a sixfold revenue climb over three years.
The milestone lands in a crowded field: Doug DeMuro's Cars & Bids raised $37M from The Chernin Group just weeks earlier, UK dealer-facing rival Motorway hit a $1B+ valuation on a $190M Series C, and the broader online car-sales wave that lifted Carvana, Vroom, and Shift is normalizing. What separates Bring a Trailer is its community-of-obsessives origin — curation and comment culture as the moat rather than dealer supply or creator reach.
First-order effects
- Sellers and buyers of enthusiast cars now have a venue processing over a billion dollars a year, meaning the collector segment's pricing discovery has effectively consolidated around one community-run marketplace.
Second-order effects
- Cars & Bids' fresh $37M raise positions it to attack the same enthusiast-auction segment directly, forcing differentiation between creator-led reach and Bring a Trailer's comment-section credibility; dealer-supplied rivals like Motorway compete for a different seller base, splitting the online auction market by inventory source.
Third-order effects
- If the pattern holds, the blog-turned-marketplace path — audience first, transaction layer second — becomes the proven entry template for vertical commerce, as it already was for CarGurus' public markets debut in the broader car-shopping space.
The trend: Online car auctions are splitting into specialist layers — enthusiast-community venues, dealer wholesale platforms, and creator-fronted marketplaces — each raising institutional capital to own its slice.
