- The reserve is the lowest bid the seller will accept. Under it, the car is not sold.
- The start price, the last bid and the screen price are not the reserve.
- A provisional bid can cost you time. It is not a purchase until the seller accepts.
An auction reserve price is the seller's floor. That floor is the reserve price. If the bidding finishes underneath it, you have not bought the car. The screen can still look busy. The car can still sit there as if it were available. None of that makes the last bid a sale.
This is the distinction, and the time a provisional bid can waste. It is not one auction's rulebook. Houses describe provisional sales in their own words. Read the conditions for the sale you are in. The idea is the same everywhere: under the reserve, the seller has not agreed.
An auction reserve price is not the screen price
The reserve price is the lowest bid the seller is willing to take. You do not always get to see it. What you do see is a start price, a current bid, or a "buy now" that may be something else entirely. Those numbers are chosen to get the bidding going, or to show where it has got to. They are not a promise that the car will sell there.
People treat the number on the screen as the price because it is the only number in front of them. Then they are surprised when the lot closes unsold, or closes as provisional. The surprise is the expensive part. You have spent the appraisal, and sometimes a holding deposit of attention, on a car that was never going to be yours at a figure that made sense.
Bid to the price the car is worth to you, after fees, transport and the work. The hidden costs of buying at auction are that stack. If your number is under the reserve, you have not lost. You have refused to pay more than the metal is worth. That is the job.
BCA buyer fees and Manheim buyer fees change the real cost of whatever bid you do land. The reserve sits under that. A bid that meets the reserve and forgets the fee is still the wrong bid.
Provisional means not sold
A provisional bid is what many online sales show when the reserve has not been met and the seller is being asked whether they will take the money anyway. It feels like a win. It is a question.
Until the seller accepts, you do not own the car. You may be asked to wait. You may be asked to raise the bid. You may hear nothing, and then see the car relisted. The time in between is not free. It is an afternoon you did not spend on the next car, and a sum you may have ring-fenced in your head as spent.
If you would rather agree a price with the owner, in one conversation, get your buying site. There is still a car to appraise. There is no hidden floor under the figure.
What to decide before you open the sale
Decide your walk-away number before the timer starts. That number is the car's value to you after the fee, the transport and the work, and it does not move because the reserve is close, or because the lot is about to close, or because you have already spent twenty minutes reading the photos. A reserve you cannot see is not an invitation to creep up. It is a reason to stop at the number you wrote down.
Read the conditions for provisional sales on that site before you bid, not after you have won a question. Some sales tell you how long the seller has to accept. Some do not. If you do not know, treat every provisional result as unfinished until a sold confirmation arrives, and keep buying other cars as if this one might vanish. It might.
A car with no reserve, or a reserve already met, is still not automatically a purchase you want. The absence of a floor does not make a damaged car clean. Do the same appraisal you would do if the reserve were high. The only thing that has changed is that your bid, if it is the highest, will actually buy it. That is a reason to be more careful, not less.
When the same car appears again, compare it with your note, not with your memory of being outbid. Memory inflates. The note says what you thought the metal was worth, and what you saw in the photos. If the new reserve sits under that note, you are looking at a price you already accepted. If the car looks worse, the note is out of date and you start again.
Treat provisional as unfinished. Do not book transport. Do not tell a customer you have the car. Do not turn down another purchase because this one is "basically yours". Basically is how double-booked money happens.
If the seller comes back above your number, you are in a new decision. The appraisal has not changed just because they want more. Say no when the new figure is a worse car than the one you valued. The fact you were the highest bidder under the reserve does not oblige you to become a worse bidder above it.
Who sets it, and why it is high
The seller sets the reserve, or the auction sets it with them. A high reserve is often a clean book price on a car that is not clean, or a private hope, or a finance number the seller needs rather than a price the market will pay. You cannot argue a reserve down by being keen in the chat. You can only bid what you will actually pay.
A car that passes through unsold is information. If it comes back next week with the same reserve, nothing has changed except the seller's patience. If the reserve drops to a number you liked, then you are looking at a different offer, and you appraise it again in case the car has picked up a new fault or a new story.
Do not confuse a reserve with a buyer's premium. The premium is what you pay on top if you win. The reserve is whether you have won. Mixing them up is how a "cheap" screen price becomes an expensive invoice, or how an unsold car becomes a morning you cannot have back.
If you would rather buy from the owner, at a price you agree in one conversation, get your buying site. There is no reserve hiding under the figure. There is still a car to appraise.
Common questions
Can I see the reserve before I bid?
Sometimes the sale shows it, and often it does not. Read that sale's rules. Do not assume the number on the screen is the floor.
What is a provisional bid?
It is a bid that has not met the reserve. The seller can still say no. Treat it as unfinished until you have a sold confirmation.
Should I bid up to the reserve if I know it?
Only if that number is still a price the car is worth to you. Knowing the reserve is not a reason to pay it.
