The collector car market is shifting — and for enthusiasts, that means opportunity.
Whether you're looking to start a collection, expand your garage, or invest in something rare and remarkable, now is a great time to get in the game. BigIron and Sullivan Auctioneers are bringing over 300 classic and collectible vehicles to auction in a two-day online event July 14 and 15, offering one of the most diverse selections of the year. It’s one of the premier collector car auctions this summer.
What’s Trending in 2025?
As the market matures, several key trends are shaping buyer interest and vehicle values:
- Modern Classics on the Rise:
Vehicles from the late '80s through early 2000s — like the Porsche 996, Mazda RX-7, and BMW M3 (E46) — are becoming increasingly sought-after. These models are appreciated for their analog driving experience, limited production runs, and nostalgic appeal among Gen X and millennial buyers.¹ - Classic Trucks & SUVs Remain Hot:
Restored Chevy Blazers, Ford Broncos, Toyota Land Cruisers, and square-body pickups continue to command strong interest. Their rugged style and versatility make them perfect for collectors who also want to drive and enjoy their vehicles.² If you're looking for classic cars and trucks for sale, this is the perfect event to explore. - Muscle Cars Still Roar, But Selectively:
While the overall muscle car market has cooled slightly, high-quality, properly restored examples — especially rare trims and original-option cars — are still performing well. Think: HEMI-powered Mopars, Boss 429 Mustangs, and early SS Chevelles.³ - Younger Buyers Are Driving Demand:
Gen X and millennial enthusiasts are now the dominant force in the collector car world. Their tastes lean toward unique styling, performance, and vehicles that balance nostalgia with usability — contributing to the rise of “neo-classics” and 1990s performance cars.³ - Online Auctions Are the New Normal:
While in-person auctions still have a place, buyers are increasingly comfortable making high-value purchases online. Transparency, detailed listings, and access to nationwide inventory have helped grow the audience — and the confidence — of digital bidders.⁴ This trend is fueling the popularity of classic car auctions online.
Auction Highlights
Over two days, hundreds of vehicles will sell through BigIron and Sullivan’s timed online platform. The lineup includes:
