How to buy a car at auction: a step-by-step guide for dealers
How to buy a car at auction as a dealer: registration, inspection, bidding, payment, collection and the costs on top of the hammer price.
· 8 min read
To buy a car at auction as a dealer, register with your company details and VAT number, study the condition report and documents, calculate your maximum bid from the price the car will fetch in your own market, bid only up to that figure, then pay within the deadline and arrange collection. Most losses happen in the calculation step, not in the bidding.
Step 1: Register as a trade buyer
Registration is the first step in buying cars at auction, and it takes longer than most new dealers expect. Trade auctions will typically ask for:
- A company register extract and the name of the authorised person.
- Your EU VAT identification number, which is checked in the VIES database.
- A copy of the bidder's ID and, on some platforms, a signed general terms document.
- A deposit, a bank guarantee or a credit limit approval before you can bid freely.
Do this a week before the sale you are interested in. Verification can take several working days, and a cross-border platform may also ask for proof that your business trades in vehicles. If you are not yet sure which auction channels suit you, read dealer auctions explained first.
Step 2: Shortlist the right cars
A good shortlist starts with what sells in your own yard, not with what looks cheap in the catalogue. Filter the auction list by the models, engines and price bands that you turn over fastest, and ignore the rest.
For each car on the shortlist, note:
- Make, model, generation and the exact engine and gearbox.
- Year of first registration and mileage.
- Tax status – margin scheme or VAT-qualifying.
- Location of the car, because that drives transport cost.
- The auction end time, so you are not calculating while the clock runs.
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 accessStep 3: Read the condition report like a buyer, not a seller
The condition report is your inspection when you cannot see the car, so read every line. Check the photos of each panel, paint thickness readings, tyre tread, listed damage with estimated repair costs and the notes from the test drive or engine start.
What to look for in particular:
- Paint readings well above factory values on one side suggest repair work that the report may not describe.
- Service history – "partial" or "unknown" will cost you on resale.
- Warning lights and fault codes – a single airbag or emissions warning can mean hundreds of euros.
- Mileage plausibility – compare it with service entries and inspection records. Our guide to the car mileage check on imported cars explains which records to use in each country.
- Keys and documents – two keys, registration papers and ideally the certificate of conformity.
If you can, view the car on site before a big purchase. Nothing replaces hearing a cold start and driving it a few hundred metres.
Step 4: Work out the numbers before the first bid
You can only bid sensibly if you know the price the car will fetch in your market and every cost between the hammer and the sale. Here is a worked example of the costs on top of the hammer price for a 2020 Škoda Octavia 2.0 TDI with about 130,000 km, bought VAT-qualifying (net) at a German auction by a German dealer. The fee and cost figures are illustrative; use your own platform's fee table and your own suppliers' prices.
| Item | Amount (net) |
|---|---|
| Hammer price | €11,000 |
| Buyer fee | €350 |
| Administration and documents | €80 |
| Transport to your yard | €450 |
| Reconditioning (valet, smart repair, tyres) | €500 |
| Inspection and registration | €150 |
| Reserve for hidden faults | €300 |
| Landed cost | €12,830 |
Now the sale side. According to listings tracked by MyCarDealer in Germany in October 2026, the median asking price of a diesel Octavia from 2019–2021 was €15,500 across 238 listings. Selling at that price in Germany, the VAT-qualifying car must carry 19% VAT on the full price: €15,500 ÷ 1.19 = €13,025 net. Your margin is €13,025 − €12,830 = €195 – before the time the car stands in stock and before any discount to the buyer.
That is a car you should not have bought at €11,000. The same exercise tells you where your limit really is. For a structured method, see car bid strategy: how to set your maximum bid.
Two warnings about the reference price:
- The median covers all body styles, trims and mileages in the period. Narrow it to the same engine, gearbox, body and a similar mileage before you rely on it.
- Asking prices are not selling prices. Allow for the discount you usually give.
MyCarDealer does exactly this narrowing – same model, generation, engine, year ±2 – and returns the market price, net margin and maximum bid in seconds; you can test it on one car with a free valuation.
Step 5: Bid with a limit, not with a feeling
Bidding is the easiest part if the limit is already written down. Enter a proxy bid at your maximum on timed auctions, or decide on the number before the lot comes up in a live sale.
Rules that keep first auctions profitable:
- Never raise the limit during the sale. If you have new information, you should have had it before.
- Watch the reserve. If the bid stops below the reserve, the car may be offered to you afterwards – you can still decline.
- Do not bid on cars you have not calculated. A "good-looking" price is not a calculation.
- Watch timed auctions to the end. Many extend the closing time when a late bid arrives, so the price can move in the final minutes.
Step 6: Payment, invoice and documents
After the win, you will receive an invoice for the hammer price and fees, usually payable within a few working days; late payment can mean storage charges or cancellation of the sale. Check before paying:
- Is the invoice issued under the margin scheme or with VAT? Under Article 226(14) of the VAT Directive, a margin-scheme invoice must carry the mention "Margin scheme – Second-hand goods" (or its equivalent in the seller's language).
- For a cross-border VAT-qualifying purchase, the seller invoices net under Article 138 of the VAT Directive and needs proof that the car left the country. Article 45a of Implementing Regulation (EU) No 282/2011 lets the seller rely on a written arrival statement from you plus transport documents, so expect to sign one. Some sellers hold a deposit equal to the VAT until the proof is in.
- Which documents travel with the car: registration certificate(s), CoC, service book, keys.
The tax side of auction invoices is explained further in what VAT margin means at a car auction.
Step 7: Collection and transport
Collection is where an auction purchase becomes real cost. Most sites give a short free storage period and then charge per day, so book transport as soon as payment clears.
Options:
- Truck transport – the standard for cross-border buying; prices depend on distance and how full the truck is.
- Driving the car yourself – possible within a country. In Germany, short-term plates (Kurzzeitkennzeichen) are issued for at most five days under § 16a of the Vehicle Registration Ordinance (FZV) and are meant for transfer, test and inspection trips; check whether the countries you cross accept them.
- Collection in batches – combining several cars from the same site lowers the cost per car.
How to buy a car at auction the first time: start small
Buy one to three cars at your first auction, in a segment you already know. The goal of the first sale is to test the whole chain – registration, payment, documents, transport and reconditioning – and to compare your calculated landed cost with the real one. Scale up only once the two numbers match.
Frequently asked questions
Is it worth buying a car at auction?
For a dealer, yes – if the car is calculated against your own retail market and you stay within your limit. Auctions give access to ex-lease, fleet and part-exchange stock in volume, but the margin is thin once fees, transport and reconditioning are added. Without a calculation, auctions are an expensive lottery.
Can the public buy at car auctions?
Trade auctions with ex-lease and fleet cars are open only to registered businesses with a VAT number. Some auction houses run separate public sales, usually for older, high-mileage or damaged vehicles, where consumer protection is very limited.
What are the risks of buying at auction?
The main risks are hidden mechanical faults not shown in the report, manipulated mileage, missing documents or keys, and overpaying in a bidding war. You reduce them by reading the report closely, checking the history, viewing expensive cars in person and bidding only up to a pre-calculated maximum.
What do I need to register as a buyer at a car auction?
Usually a company register extract, an EU VAT number that passes the VIES check, the bidder's ID and sometimes a deposit or credit approval. Allow several working days for verification.
Which costs should I budget for on top of the hammer price?
Buyer fee, administration and document fees, transport, storage after the free period, reconditioning, inspection and registration, and a reserve for hidden faults. Fees carry VAT. Add them all to every lot before deciding on your maximum bid.
