The differences at a glance

Comparison of auctioning via Octane with Dealer, per aspect
Aspect	Auction via Octane	Dealer
Speed	Seven days of bidding; one to two weeks from submission to close	Often arranged within days(advantage)
Proceeds	Market value: buyers bid against each other(advantage)	Trade buy-in price: resale price minus margin, reconditioning and risk
Negotiating	Not needed, the bidding process does the work(advantage)	A professional negotiates for the lowest possible price
Middleman	Straight to the end user(advantage)	The dealer still has to earn on the resale
Appreciation of details	Enthusiasts pay for rare options, history and originality(advantage)	Standard buy-in formula and resaleability
Transparency	Open auction, all bids visible(advantage)	Internal calculation, one offer
Audience	Buyers in 12 Western European countries(advantage)	One buyer: the dealer
Settlement	Private chat with the buyer; we guide the handover	The dealer handles everything, on their terms
Price protection	Confidential reserve, agreed together beforehand(advantage)	None: accept the offer or walk away
Cost to you	No seller commission; only your own photos, or a photographer from our network	No direct costs; the difference is in the price

In short

Selling to a dealer suits you if:

you want to sell within days and accept the price difference
your car is a common model without special features
you would rather deal with one party than run a sales process

An auction via Octane suits you if:

your car is special: rare specification, good history or low mileage
you want market value rather than a trade buy-in price
you can wait one to two weeks for the result

Already have a dealer offer? Use it as the reference for your reserve: then you never sell for less at auction.

Who Each Option Suits

Selling to a dealer suits a limited number of situations: when speed is your absolute priority and the financial difference does not matter to you, or when your car is a common model without special features. A three-year-old Skoda Octavia sells fine through a dealer, and the price difference is then limited.

As soon as your car is special, the situation changes completely. A dealer looks at your classic Alfa Romeo, your low-mileage BMW M car or your well-documented Porsche and mainly sees the risk and effort of reselling it through their own channels. Their offer reflects that, not the actual value to an enthusiast.

On an auction platform you reach buyers who are specifically looking for your type of car. They judge your car on its own merits: the condition, the history, the specification, the story. And because several buyers bid at the same time, the market sets a fair price instead of a dealer. If you are buying another car at the same time, also read auction vs. trade-in. And if you do want to sell directly to a dealer, you can through selling directly: a non-binding offer from a dealer in our network, free for you.

Why an auction via Octane

Octane skips the middleman. Your car goes straight to the enthusiast who wants to pay what it is worth to them, not what a trader thinks they can resell it for. That difference is greatest for cars a dealer can do little with: niche models, classics and cars with special specifications that are hard to place through regular trade channels.

Around every auction we run a targeted campaign (our own channels, e-mail alerts, advertising in the Netherlands and the rest of Western Europe) and verified buyers bid against each other for seven days. A dealer offers a fixed amount, once, on their terms. As the seller you pay Octane no commission.

If your car does not fit the platform, for example because it is a tidy daily driver or a young used car, we say so honestly. With your consent we can then bring it to the attention of dealers who are looking for exactly such cars, for a direct purchase from you as the owner.

How the reserve works

In an Octane auction you can set a reserve: a minimum price below which your car will not be sold. Three things to know:

Confidential

Bidders can see that there is a reserve, but not how high. They bid on what the car is worth to them, not on your floor.

Agreed together

You set the reserve with our team before the auction, based on comparable auction results. A dealer’s offer or a trade-in value can be a good starting point.

Not met? No obligation

If the highest bid stays below the reserve, the car is not sold and you are not bound to anything. We then look with you and the highest bidder at whether a deal is still possible.

Prefer to auction without a reserve? That is possible too; discuss it with our team.

Frequently Asked Questions

That differs per car. A dealer works back from their resale price, minus margin, reconditioning and risk; at auction, buyers decide what the car is worth to them. The more special the car, the bigger the difference tends to be. Feel free to get a dealer offer and discuss it with our team as the reference for your reserve.

If the offer is close to market value, that is a fine starting point. Use it as your reserve: then you never sell for less at auction, with the chance of more. If the reserve is not met, you can still take the dealer up on the offer.

In terms of convenience the dealer wins, that is true. At Octane you supply photos per the photo guide (or via a photographer from our network) and answer bidder questions; we do the text, the campaign and the bidding process. The difference in convenience is small, the difference in proceeds can be large.

Octane focuses on private enthusiasts, but traders are not excluded. Every bidder is verified and pays the same buyer fee; for you as the seller it makes no difference who places the highest bid.

If it really has to happen within a few days, a dealer is the fastest option. If you can wait one to two weeks, an auction can yield considerably more. Weigh up what those extra weeks are worth to you.

If the reserve is not met, you are not bound to anything. We look with you and the highest bidder at whether a deal is still possible; otherwise you can still sell to a dealer or consider a new auction with a different reserve.

As the seller you pay no commission. The buyer pays a 3% buyer fee including VAT, with a minimum of €350 and a maximum of €3,600. You supply the photos yourself per the photo guide, or pay a photographer from our network directly.
