Selling a car at auction can be a straightforward and effective way to achieve a competitive price - provided you understand the process and choose the right auction partner.
In this guide, we'll walk you through how to sell a car at auction step by step, explaining what documentation you'll need and how your car is valued, listed and then sold. You'll also find answers to common questions and practical tips to help you feel confident throughout the process.
Find and register with a reputable auction house
The company you choose to auction your car can make a big difference to your experience. When choosing a car auction house, consider these three factors:
- Experience: How long have they been selling cars for? Do they have any specialisms? What do their customers say about them?
- Pricing: Do they operate via an entry or listing fee? Are there any hidden costs, i.e. for photography or vehicle collection? And how do they calculate their seller's commission?
- Marketing: Ask how they actively promote the cars they're listing? Do they use modern marketing tactics such as social media?
At Aston Barclay, we run both online and in-person auctions to ensure you have the best opportunity to sell your vehicle. Auctions run across five locations: Chelmsford, Donington Park, Prees Heath, Wakefield and Westbury. We also offer car transportation services, whereby our friendly team comes to inspect and collect your vehicle on your behalf. Our national door-to-door collection services eliminate the stress of getting your car to auction.
Getting your car in front of the right prospects is essential. Which is why we take an innovative approach to marketing and promotion. With our dedicated in-house Buyer Executives and the LCV Hub, it's easy to see why we won the WhatVan? Remarketing Award in 2025.

1. Gather relevant documentation
Before your car can be entered into an auction, you’ll need to ensure you have all the relevant documentation and other essential items. Having everything ready to go helps the auction house assess your vehicle accurately and reassures potential buyers.
Things you must have typically include:
- V5C registration document (logbook)
- Current MOT certificate, where applicable
- All sets of keys, including spare keys
- SatNav discs or SD cards, if originally supplied
- Service history and maintenance records, including historic garage receipts
Missing paperwork can reduce buyer confidence and may impact the final sale price.
2. Take your car for valuation
When you sell a car at auction, it'll have to undergo an inspection by your chosen auction house. They also may ask for further information on your vehicle if needed. As mentioned, some auction houses offer a vehicle collection service, making the valuation super easy and stress-free.
During the valuation, they'll be looking at things like the vehicle's:
- Model and year
- Mileage
- History and wear and tear, including dents and previous write-offs
- MOT status
Broadly speaking, they'll be reviewing market demand for your vehicle. Once they have considered everything, they'll provide you with pricing guidance.
3. Creating the listing
Once your car is valued and you're happy to list it, we'll ask you to complete our seller's form and provide identification to confirm that you're entitled to sell the vehicle. Next, it's time to get your car on the market and in front of potential buyers.
This is done via a listing that consists of photographs of the car, details and a price guide. Your car will be given a lot number – a unique identification number used in both in-person and online auctions. Should you choose to sell your car at auction with Aston Barclay, we would post your car's listing on our LVC Hub – our online portal where sellers and buyers can easily access thousands of vehicles and get live updates of upcoming auctions.
Most auction houses will allow you to choose a reserve price. This is the lowest amount you'd be willing to take at auction – it’s a great safety net to ensure both you and the auctioneer are happy. If the bids don't reach your reserve price in the auction, your vehicle will not be sold for less than the reserve without your prior consent.
4. Time for the auction!
It's now time to sell your car at auction. Once your car enters the auction, its key details will be announced to bidders, either in the auction hall or online. Interested buyers will place bids – in a live auction, this is done by raising a paddle. Remember, a bid is legally binding, and once it is submitted, it must be honoured.
Bidding usually lasts just a few minutes. When the hammer falls, the highest bidder at that moment is successful. If bidding doesn't reach your agreed reserve price, there may still be an opportunity to negotiate with the interested buyer after the auction. We may take a provisional bid. If we do, we'll contact you and the bidder so you can try to reach an agreement on the sale price.
5. Processing the sale
To complete the sale, the buyer is required to make payment within a few working days. Once the cleared funds have been received, the proceeds will be transferred to you, minus the seller's fee and any applicable charges. We'll then release the relevant documentation to the new owner, update the registered keeper details using the V5C, and remove your vehicle from all Aston Barclay advertising channels.
Every vehicle that we sell is sold in line with Aston Barclay’s General Conditions of Auction, which set out the full terms.
FAQs about selling a car at auction
What happens if my car doesn't sell at auction?
If it doesn't sell at the first auction, your car will automatically be entered into the next suitable auction – and with multiple auctions happening each week, it'll get snapped up in no time!
How long does it take to sell my car at auction?
Selling a car at auction, from preparation to sorting the post-sale paperwork, typically takes anywhere from 10 days to just over two weeks. This allows time to prepare the vehicle and gather paperwork, which often takes about a week, followed by entry into the next suitable live auction, usually within another week. Once the car has been sold, the post‑sale process generally takes several days.
How can I prepare my car before selling it at auction?
A well‑prepared car is more appealing to buyers and can help drive stronger bidding. Focus on presentation and a few simple checks before auction day.
- Clean it thoroughly: Make sure the car is spotless inside and out. Clean carpets and polished paintwork all help create a positive first impression.
- Sort small, obvious issues: Replace blown bulbs, refit loose trim and fix minor damage like cracked mirrors. These low‑cost fixes remove common reasons that bidders use to lower their offers.
- Check the tyres: Tyre condition is one of the first things buyers notice. Even wear and legal tread depth show the car is road‑ready and well cared for.
