The most common deception: online valuation as a hook
Direct buying platforms generate their business by purchasing cheap cars and reselling them with a margin. To get in-person visits, many of them offer online valuations that give attractive figures, but these are non-binding and drop significantly during the physical inspection.
The process is familiar: you enter the car details, receive an estimate that seems reasonable, go to the appointment, and the valuer applies discounts for details you never mentioned because no one asked you specifically. Scratches on the bodywork, tyre wear, upholstery with signs of use, the absence of the spare key.
It is not illegal. It is a business model. But if you understand how it works, you can protect yourself: take detailed photos of the car before the appointment, ask for the applied discounts to be detailed in writing, and, above all, compare with at least one other platform before accepting.
If you understand how these platforms work, you can protect yourself. The article about what is behind direct buying platforms explains this in detail.
The surprise discount during the in-person inspection
A variation of the previous one that deserves its own section: the valuer who does the inspection, validates the online price, and then, right before signing, brings up an additional defect they hadn't mentioned. At that moment, the seller has already invested time, has travelled, and is psychologically prepared to close the deal. The cost of rejecting the offer seems greater than accepting the discount.
It is a negotiation technique known as "foot-in-the-door" applied in reverse: first they get you to reach an agreement, and then they modify the terms when walking away has a high perceived cost.
The most effective defence is mental: before the visit, decide on your minimum price and commit to rejecting any offer below it, regardless of how advanced the process is. An offer below your minimum is an offer you must reject, no matter how much time has already been invested.
The private buyer who negotiates at the last minute
In private sales, the most common variation occurs at the closing moment: the buyer comes to see the car, shows interest, agrees to buy it at the set price, and then, just before signing or paying, introduces a new objection to lower the price.
The most frequent excuses: "I saw the exact same one cheaper this morning", "My mechanic told me it has an issue", "I only have exactly this much money, can't you do something?". The goal is always the same: to get a last-minute discount by taking advantage of the fact that you already have the buyer in front of you and the process is almost closed.
The defence: do not confirm the sale verbally before being paid. Until the money is in your account or in your hand, the sale is not closed. If the buyer tries to lower the price at the last minute without a new and verifiable technical reason, you have every right to maintain the price or decline the sale.
Deferred payment or cash without a contract
Two clear warning signs that appear in documented scams in the private sale of cars:
The buyer who asks to take the car and pay later, "as soon as the bank does the transfer" or "tomorrow when I get paid". Never hand over the car without having received payment. Without exception. If the buyer cannot pay at the moment, the sale is not closed.
The buyer who insists on paying a large amount in cash without signing any contract. Cash leaves no trace, and without a signed contract you have no documentation of the transaction. In the event of any subsequent claim, you would be in a very vulnerable position. For the change of ownership at the DGT, you will need the signed purchase and sale contract anyway.
Always use a purchase and sale contract signed by both parties. The free Dealcar template includes all the necessary fields.

Time pressure: "I can only do today"
Both on direct buying platforms and with private buyers, time pressure is a common negotiation tactic. "This offer is only valid today", "If you don't confirm now, I have another interested party", "The company promotion ends at the end of the month".
The goal is to stop you from comparing. A seller who has time to ask for another valuation or to wait for another buyer has more bargaining power than one who feels they will lose the opportunity if they do not accept immediately.
The reality: direct buying offers almost never actually expire in 24-48 hours. If a private buyer disappears because you don't accept immediately, they were probably a buyer who was going to negotiate downwards anyway. The second-hand market has enough buyers for one who leaves to be replaced by another.
The valuer looking for defects you can't see
During the in-person inspection of any direct buying platform, the valuer is trained to find defects. Not because the car necessarily has them, but because each documented defect justifies a discount on the guide figure.
Some of these defects are real and reasonable. Others are subjective or minor and are used to adjust the price towards the margin the company needs. The difference is not always easy to detect if you do not have experience in the sector.
What you can do: before going to the appointment, check the car thoroughly yourself. Photograph any existing imperfection. Check the DGT history to know what is on the official registry. If the valuer mentions a defect you do not recognise, ask them to show you physically and to have it detailed in the written offer. A respectable valuer will have no problem doing so.
Before any in-person valuation, knowing precisely how much your car is worth on the market gives you a solid benchmark to evaluate any offer.
How to protect yourself: what you must always do
These practices significantly reduce the risk of ending up in an disadvantageous situation:
Always compare in more than one place. A single offer, whether from a platform or a private individual, is not a market reference. Receiving several offers from professional buyers gives you real context to evaluate if a figure is good or not. The difference between the first offer and the best one can be hundreds of pounds.
Define your minimum price before any negotiation. Not at the moment of negotiating, but beforehand. Emotion-driven pressure during negotiation makes rational decision-making difficult. If you have a clear and predefined minimum, it is easier to stick to it.
Never hand over the car without being paid. No exceptions. Neither to private individuals nor to platforms. Transfer received in your account or cash in hand before the keys change hands.
Always sign a sales contract. Even with a trusted private individual. The contract documents the agreed terms, protects against claims, and is necessary for the change of ownership.
Notify the DGT of the sale immediately. Once the car is handed over, report the transfer on the DGT electronic headquarters to avoid future fines coming in your name. To find out all the steps of the process, the article about procedures to sell a car outlines them one by one.
Dealcar: no surprises or renegotiations

Frequently Asked Questions
Are direct buying platforms obliged to respect the online valuation?
No. Online valuations are guide estimates, not binding offers. The final offer is set after the in-person inspection. This is legal and common practice in the sector. What you can do is ask for the applied discounts to be detailed in writing to understand what justifies them.
What should I do if a private buyer asks me to take the car before paying?
Reject it without hesitation. Never hand over the car without being paid, regardless of the trust the buyer conveys or the verbal guarantees they offer. The transfer must be confirmed in your account before handing over the keys.
Is it legal to sell a car in cash?
Yes, with a caveat: for transactions exceeding €1,000 between individuals, Spanish law limits cash payments. Above that figure, the payment must be traceable (transfer, cheque). Furthermore, without a written contract, the sale has no documentary support in the event of any subsequent claim.
How do I know if the offer made to me is good?
By comparing it with at least one other offer from a different platform and with the price of similar cars advertised on private portals. If the offer is more than 20% below the market price between private individuals without a clear technical justification, it is a sign that there is margin to get more elsewhere.
What happens if I sell the car and then the buyer claims it had hidden defects?
If you declared all known defects in the purchase and sale contract, you are protected. If you hid significant defects that you knew about, the buyer can claim for hidden faults for 6 months. That is why transparency in the sales process is not just ethical: it also protects you legally.
