Which Platform Should You Sell On?
The right venue depends on what you're selling, not which platform is “better.” Here's how the data breaks down by car type.
Modern sports cars, JDM, and 1980s–2000s enthusiast cars
→ Cars & BidsC&B's top makes — BMW, Porsche, Mercedes-Benz, Toyota — mirror exactly what sells well there. With a free listing and a community built around this era of car, it's the natural home for a well-documented E46 M3, Supra, or early 911. The median sale of $17,250 tells you the audience is here for these cars.
Pre-1980s classics, exotics, and six-figure collector cars
→ Bring a TrailerBaT's top makes include Porsche, Ford, Mercedes-Benz (muscle, Corvette) and its highest recorded sale hit $4,400,000. If your car is a vintage Ferrari, early American muscle, or a rare European classic, BaT's larger, wealthier bidder base and average sale of $51,443 make it the better platform to reach serious collectors.
Sub-$20K daily drivers and project cars
→ Either, but C&B has lower upfront costBoth platforms sell cars in this range — C&B's p25 is $9,123, BaT's is $12,500. For a $10–15K car, C&B's free listing means you keep more net. BaT's $99 Classic listing fee is worth it if your car suits the BaT audience (vintage, rare, or particularly well-documented).
Which Gets Better Prices?
Bring a Trailer's average sale price ($51,443) is nearly 1.8× Cars & Bids' ($28,012), and its median ($24,500) is about 42% higher than C&B's ($17,250). But before you conclude BaT “gets better prices,” consider the mix.
The mix effect: BaT's higher averages reflect its inventory — more classics, more exotics, more pre-1980s cars that inherently command higher prices regardless of venue. This doesn't mean BaT will get you more money for the same car. A 2005 BMW M3 will likely sell for a comparable number on either platform; the bidder pools for that car overlap significantly. Friday's Watchlist's Fair Value Estimator uses comps from both platforms so you can see what your specific car is actually worth, not just what the average car on each platform sells for.

It depends on the car. Bring a Trailer is better for classics, high-end exotics, and anything pre-1980s — it runs ~3× more auctions and sees average sales of $51,443. Cars & Bids is better for modern enthusiast cars (1980s–present) with a free seller listing and a lower median sale price of $17,250 that reflects its younger, more affordable inventory.
