Reserve vs no-reserve on Bring a Trailer: which gets a stronger result?

Ask ten consignors about reserve vs no-reserve and you'll get the same opinion ten times: "No-reserve always sells higher." It's the kind of advice that's right often enough to feel like a rule and wrong often enough to cost real money when it gets misapplied.

The case for no-reserve

BaT's audience rewards no-reserve listings with more bids, more comments, more attention, and — most of the time — a higher final price. The mechanism is psychological: a no-reserve auction reads as "this car is selling," which makes serious buyers commit early instead of waiting to see if the seller bails. More commitment, more competition, better outcome.

On cars with strong comps in the $20K–$80K range and broad enthusiast appeal — a clean 911, a tasteful E30 M3, a well-documented BMW Z3 — no-reserve almost always wins. The downside risk is small because the comps support a floor.

When reserve is the right call

Reserve makes sense in three situations:

• Thin comps. If your car has fewer than three relevant sales in the last 12 months, you don't know what the floor is. A reserve protects you while still letting the market discover the price.
• High-dollar cars. Above roughly $150K, the pool of qualified bidders shrinks. A single no-show or a slow week can leave you with a result well below comp. A reserve is cheap insurance.
• Unusual configurations. Rare options, one-of-a-kind builds, restomods — anything where "the comp" is really just one or two prior sales. The market may need time to find the right buyer.

The cost of getting it wrong

We've watched no-reserve listings on rare cars finish $15K–$40K below comp because the right buyer happened to be on vacation that week. We've also watched reserved listings on common cars finish well below their no-reserve potential because cautious bidders never got past the "is this really selling?" question.

How we decide

For every consignment, we pull the comps, look at the car's specific market, and recommend reserve / no-reserve with a clear reason. If we recommend reserve, we set it conservatively — at or just below the bottom of the comp range — so the auction has room to run.
