Bring a Trailer’s Online Auction Community Sees Record Growth in 2025

Automotive auction platform and enthusiast community Bring a Trailer (BaT) set a new high-water mark in 2025, surpassing previous years with more than $1.7 billion in sales and marking the fourth consecutive year in which that number exceeded $1 billion. BaT also saw its highest volume of listings, with 49,486 total auctions split between cars, trucks, motorcycles, memorabilia and parts, at an 81% sell-through rate. On average, the site hosted 951 auction listings per week, with a high of over 1,200. 

“The numbers are great, but we chase more than numbers at Bring a Trailer. Our ethos is transparency, depth of presentation, and an open microphone for people to comment freely with their expertise, experience, and opinions,” said Randy Nonnenberg, the company’s co-founder and president. “We hit 50,000 listings in 2021 after seven years in the auction business. In 2025, we did that number in a single year  The goal for 2026 is to continue bringing our unique mix of trustworthy, visible buying and selling experiences to as many people as possible around the world.”

The BaT community also continued to grow, with an 11% increase in registered users – over double 2024’s gain – for a total of 1.65 million. The platform also saw a spike in cars sold for over $1,000,000, with 48 cars crossing the seven-figure mark. And the growth is not limited to online, as BaT hosted 13 events, their most ever, at locations around the world with thousands of attendees. 

Below are some of the most noteworthy highlights from Bring a Trailer in 2025.

The Gran Turismo Generation 
As more millennial and Gen Z buyers enter the market, the trend toward late model classics grew again in 2025, with vehicles from the early 2000s dominating auction listings for the third consecutive year. In order of volume, the most listed model years on BaT in 2025 were 2006, 2004, 2008, 2005 and 2007 – essentially a repeat of 2024.

“As the most-listed cars on the site, those from the early part of the millennium continue to indicate an “end-of-analog” trend among collectors. Special cars from this era offer relatively modern convenience and drivability, unencumbered by the screens and heavy curb weights we’ve come to expect from current manufacturers,” said Nonnenberg. “Our community continues to be vocal and passionate about these accessible classics and their continually rising values. The 4,800-mile 2001 Integra Type R was an outstanding example of that.”
