How to Run an Online Car Auction

Get the paperwork together first

Every vehicle needs its ownership and registration documents, its keys (note how many sets) and, where it applies, its roadworthiness certificate and service record. Check that each vehicle is yours to sell and free of outstanding finance — many countries have vehicle history services that show finance, theft and write-off markers. Which documents a buyer must receive, and in what form, is set by local law, so check the rules where you sell.

Write an honest condition report

• Mileage, and whether it is verified.
• Service history, test or inspection expiry and any recent work.
• Every known fault, and every damaged panel photographed.
• Whether it starts, drives and is road-legal — or is sold as a non-runner or for parts.
• Any insurance write-off or salvage marker the vehicle carries.

Many countries give sellers specific duties to disclose mileage and damage. A thorough report protects you as much as the buyer.

Photograph every vehicle the same way

Use a consistent set for each vehicle: front and rear three-quarters, both sides, the interior front and rear, the dashboard showing the mileage, the engine bay, the tyres, and close-ups of any damage. A short video of the car starting and running, hosted on a video site and linked from the listing, answers most questions before they are asked.

Decide who can bid

Trade-only and public sales work differently: trade buyers expect less hand-holding and pay faster; the public needs more reassurance. Either way, require every bidder to register and accept your terms, and on higher-value vehicles consider requiring a card on file before bidding.

Set reserves and closing times

Most roadworthy vehicles carry a reserve close to trade value; salvage and non-runners often sell better without one. Close vehicles a few minutes apart and use soft close, so a late bid extends the clock rather than taking the car in the last second. Letting buyers leave a maximum bid in advance helps dealers who cannot watch the close.

Payment, handover and transfer

Take full payment before handover — by card for smaller amounts, by bank transfer for most vehicles — and release the car and keys only once funds have cleared. Complete the change of ownership the way your country requires, and state collection or delivery arrangements on every lot so buyers can price transport into their bid.

When a vehicle does not sell

If bidding ends below the reserve, you can offer the vehicle to the highest bidder at their bid, invite offers for a short period after the close, or enter it in your next sale — often with a lower reserve and better photographs.

Frequently asked questions

What should an online car auction listing include?

Make, model, year, mileage, service history, test status, number of keys, every known fault with the damage photographed, any write-off or salvage marker, where the car is and how collection works.

Do cars in an online auction need a reserve?

Most roadworthy vehicles carry one, close to trade value. Salvage and non-runners are often sold without, because a low start attracts more bidders.

How do buyers pay for a car bought at online auction?

Usually by bank transfer, or by card for smaller amounts. Release the vehicle and keys only once payment has cleared.

Can I sell damaged or non-running vehicles online?

Yes — say clearly that the vehicle is damaged or does not run, photograph the damage and declare any salvage or write-off marker. Disposal and registration rules for such vehicles vary by country, so check them before listing.
