Comparison
Private Match vs. Bring a Trailer: The Real Math
Bring a Trailer is the right buyer for some cars and the wrong buyer for others. This post walks through the side-by-side economics of a BaT auction vs. a Fast Auto Exit private buyer-network match. Fees, timing, risk, and a worked example on a 200,000 dollar Porsche 911 GT3 Touring.
BaT seller economics
Bring a Trailer charges a 5 percent seller's commission on the hammer price, capped at 7,500 dollars. There is no listing fee on accepted cars. The buyer pays a 5 percent buyer's premium (capped at 7,500 dollars), so the hammer price is roughly 95 percent of what the buyer actually paid.
Beyond the commission, the seller is responsible for: photographing the car (or hiring a photographer, typically 500 to 1,500 dollars), writing the listing, responding to commenter questions during the 7-day auction, arranging escrow coordination, and handling title transfer paperwork.
Time from listing decision to wire received: typically 6 to 12 weeks. Pre-listing prep 2 to 4 weeks, auction 1 week, payment and transport coordination 1 to 4 weeks.
Fast Auto Exit match-making economics
Fast Auto Exit is not a buyer and not an auction house. We are a private match-making service. We surface your listing under NDA to qualified buyers in our network, introduce both parties when there is interest, and earn a documented match-making commission from each side at closing. The commission is disclosed in writing before any introduction and is the same regardless of price (which keeps us neutral on the negotiation).
You and the buyer negotiate price directly. The buyer wires funds to you directly (or pays via certified funds or third-party escrow you both agree on). The buyer arranges and pays for transport. We invoice our commission separately to each side after closing.
Time from submission to buyer introduction: typically under 7 days. Time from submission to wire received: typically 2 to 4 weeks depending on transport scheduling and DMV title processing.
The worked example
A 2019 Porsche 911 GT3 Touring in excellent condition, 12,000 miles, complete service history, original paint, no stories. Retail comparable: 200,000 dollars.
Path A: Bring a Trailer
- Hammer price (expected range): 185,000 to 210,000
- Median outcome: 197,500
- BaT seller's commission (5 percent, capped at 7,500): minus 7,500
- Professional photographer: minus 800
- Pre-sale detail and prep: minus 500
- Title services partner (escrow handling): minus 199
- Net to seller: 188,501
- Timeline: 8 to 12 weeks
- Risk: auction may not hit reserve, or may hit a soft number
Path B: Fast Auto Exit private match
- Negotiated direct price (expected range based on private comparables): 185,000 to 200,000
- Median outcome: 192,500
- Match-making commission (seller side, disclosed pre-introduction): per disclosure
- Transport cost: 0 (buyer arranges and pays from your location)
- Title transfer cost: per state DMV, typically split per the bill of sale
- Net to seller: 192,500 minus disclosed commission
- Timeline: 2 to 4 weeks from submission to wire
- Risk: negotiated direct price is firm once both sides sign
When BaT wins
BaT wins when public auction tension drives the price above the private comparable. That tends to happen on:
- Cars with strong enthusiast followings (air-cooled 911s, GT3 RS, manual-transmission specials)
- Low-mileage cars with full documentation
- Original-paint, unmodified configurations
- Halo configurations (rare color combinations, sought-after options packages)
- Cars priced 50K to 250K where the BaT commission cap is binding (commission stays at 7,500 even as the hammer rises)
When the private match wins
The private match wins when:
- You need the wire in weeks, not months
- The car has documentation gaps that would cap BaT bidding
- The car is a less-collected model that does not attract a BaT bidding war
- You do not want to manage the 7-day auction process and the comment section
- You are an estate executor on a multi-car timeline
- You are a divorcing party where speed, certainty, and confidentiality matter
- You are a busy professional whose time is worth more than the BaT-vs-private spread
- You want a private price record (BaT prices are public and searchable)
The honest recommendation
For exceptional cars (concours-grade, documented provenance, halo models in unusual configurations), BaT or a major auction house will often net you more. For everything else, a private match is competitive on net and structurally better on timing.
We tell sellers honestly when their car looks like it would do better at BaT. We are not interested in matching a transaction where the seller would have netted more elsewhere. Our reputation depends on getting that recommendation right and our commission only triggers if the introduction closes anyway, so there is no business reason for us to push a match-making transaction that does not fit.
Submit your car and we will share our honest read on whether BaT, RM Sotheby's, Mecum, or our private network is the right channel for you.
