How to sell a car at auction: offloading aged dealer stock
When should a dealer sell a car at auction instead of retailing it? Costs, reserve prices, timing and how to choose which aged stock goes to auction first.
· 8 min read
To sell a car at auction as a dealer, compare the expected auction net – hammer price minus seller fees, transport and preparation – with what the car will cost you to keep until it retails. If holding it costs more than the discount you take at auction, send it. Set a reserve based on current trade value, not on what you paid, and enter it while there is still demand.
When auction beats retail for a dealer
Selling at auction is better than retailing when the car will cost you more in time, money and attention than the discount you accept by selling it wholesale. That usually applies to:
- Aged stock – cars that have passed your normal stock turn without serious interest.
- Part-exchanges outside your segment – the old city car taken in against an SUV, or a premium car on a budget forecourt.
- High-mileage or older cars that need more reconditioning than they can recover at retail.
- The wrong fuel or gearbox for your market – a manual diesel where your buyers want petrol automatics.
- Cars with problems you do not want to warrant – known faults, unclear history, cosmetic damage you will not repair.
Auction is not a failure. It is a tool for turning unproductive stock back into capital that can buy faster-selling cars. Tracking which cars become aged in the first place is covered in used car inventory management.
Holding cost vs auction net: the core decision
The decision comes down to two numbers: what the car will bring at auction after costs, and what it costs to keep trying to retail it.
Holding cost per month typically includes:
- Interest or opportunity cost of the capital tied up.
- Value loss as the car gets older and the market moves.
- Insurance, space and preparation repeated for each new round of photos.
- Advertising and the price reductions you will need to make.
Worked example (illustrative figures): a 2019 Ford Focus taken in part-exchange, in stock for 100 days, asking €12,500 with almost no enquiries. Your book cost is €10,200.
| Option | Expected result |
|---|---|
| Keep retailing: likely sale in 2 more months at €11,700 after reductions | €11,700 − €10,200 − 2 × €180 holding cost = €1,140 gross before VAT on the margin |
| Auction now: hammer €10,300, seller fee €250, transport €150 | €10,300 − €10,200 − €400 = −€300 |
On these numbers you would keep the car – but only if the €11,700 sale price is realistic. If the market says otherwise, the picture changes.
That is where the market check matters. According to listings tracked by MyCarDealer in October 2026, the median asking price of a Ford Focus from 2018–2020 was €11,000 in Germany (374 listings), €11,750 in Belgium, €11,790 in the Netherlands, €11,900 in Italy and €9,036 in Poland. Across all these countries, the middle half of the listings sat between €9,400 and €13,880. A Focus at €12,500 in Germany is priced above most of its competition; either the price comes down, or the car goes.
For car dealers
Know your margin before you buy
MyCarDealer compares any car from an auction or listing with the market in your country and shows the net margin after VAT, transport and costs – and the maximum bid.
Request accessHow to sell a car at auction: step by step
Selling through a trade auction follows the same pattern on most platforms:
- Register as a seller. Company documents, VAT number and bank details.
- Prepare the car properly but cheaply. A good valet and honest photos; no expensive repairs that the trade will not pay for.
- Commission or complete the condition report. Buyers bid on the report. Accurate reports reduce disputes and returns.
- Collect the documents. Registration papers, service book, both keys, certificate of conformity if available.
- Choose the format and sale date – timed online, live online or a physical sale.
- Set the reserve.
- Transport the car to the auction site or, on online platforms, leave it at your premises for collection.
- Invoice correctly. If you sell under the margin scheme, the invoice must carry the mention "Margin scheme – Second-hand goods" under Article 226(14) of the VAT Directive (2006/112/EC), and under Article 325 the VAT may not be shown separately.
Selling cross-border to dealers in other member states is possible on most online platforms; for VAT-qualifying cars, the exemption under Article 138 requires the buyer's valid VAT number and proof that the car left your country.
How to set a sensible reserve price
A sensible reserve is the lowest price at which selling today is better than keeping the car – based on current trade value, not on your purchase price. What you paid is a sunk cost; the market does not know or care.
To set it:
- Find the current retail median of comparable cars in your market.
- Deduct what a buying dealer will need: VAT on the margin or the full price, fees, transport, reconditioning and their profit. That is roughly what the trade will bid.
- Compare that figure with your holding-cost alternative.
- Set the reserve at or slightly below the point where auction and holding break even.
Reserves set too high are the most common reason why dealer cars return unsold from auction – and come back older and with a second set of transport and fee costs. If you are not willing to sell at the trade level, do not send the car.
What it costs a dealer to sell at auction
Selling costs are lower than buying costs, but they add up. Expect:
- Seller fee – a fixed fee or a percentage, depending on the platform and price band.
- Entry or listing fee – on some platforms, payable even if the car does not sell.
- Condition report or inspection fee.
- Transport to the auction site if it is a physical sale.
- Re-entry fees if the car does not sell and is offered again.
- Preparation – valet and photography.
Check the current fee table of each platform; they vary considerably, and online platforms often charge less because no physical handling is involved.
Which aged stock should go to auction first
Send first the cars where the gap between your asking price and the market is largest, and where holding costs are highest. A simple ranking:
- Cars over your stock-turn target with no enquiries in the last two weeks.
- Cars priced well above the market median that you are not willing to reduce.
- High-value cars – their holding cost per day is higher in absolute terms.
- Cars entering a weak season – convertibles before winter, four-wheel drives in late spring.
- Models about to be replaced by a facelift or a new generation.
High-mileage cars deserve particular attention. According to listings tracked by MyCarDealer in Germany in October 2026, diesel Škoda Octavias from 2017–2018 had a median asking price of €11,799 across 160 listings, and the median mileage across European listings for that age was around 170,000 km. Cars well above that mileage band struggle at retail and are often better in the trade, where exporters and high-mileage specialists bid for them.
Selling into the right market
The best trade price for a car may come from another country. If your market undervalues a model – for example, small cars in Poland are generally cheaper than in Western Europe – a cross-border online auction exposes the car to buyers in markets where it is worth more.
MyCarDealer shows what a car would fetch at retail in each market from current listings, which helps decide between retailing at home, selling at auction locally or offering it to dealers abroad. You can check one car with a free valuation.

Frequently asked questions
Is it worth selling a car at auction?
For a dealer, yes, when the car would cost more to keep than the discount you accept by selling it wholesale. Auction turns aged stock, part-exchanges outside your segment and high-mileage cars back into capital quickly, so you can buy cars that sell faster.
How does selling a car at auction work?
You register as a seller, prepare and photograph the car, provide or commission a condition report and documents, choose a sale format and date and set a reserve. If the highest bid meets the reserve, the car is sold; you invoice the buyer and hand over the car and documents after payment.
How do I set a sensible reserve price?
Base it on current trade value, not on what you paid. Take the retail median of comparable cars, deduct what a buying dealer needs for VAT, costs and profit, compare the result with your holding costs and set the reserve at about the break-even point.
What does it cost a dealer to sell a car at auction?
Seller fees, sometimes entry or listing fees, condition report fees, transport to a physical sale, valeting and photography, and re-entry fees if the car does not sell. Each platform publishes its own fee table, and the costs differ widely.
Can you just turn up to a car auction?
At trade auctions, no – sellers and buyers must be registered businesses, usually with a VAT number, before they can enter cars or bid. Public auctions may allow walk-in visitors to view and bid, but dealers selling stock normally use trade sales.
