Frequently asked questions
What information is obtained with the number plate and what is not
When you enter your number plate into an online valuator, the system queries the DGT (Directorate-General for Traffic) records to extract the basic details of the vehicle: make, model, version, engine capacity, fuel type, gearbox type, date of first registration and, in some cases, the number of previous owners.
Read also what the latest DGT number plate tells you about your car's value.
With that information, the valuator cross-references the vehicle with registered transactions of similar vehicles and returns an approximate value range. It is an automatic process that takes between 10 and 30 seconds and provides a useful first approximation.
What the number plate cannot tell the valuator is the actual condition of the car. The current mileage, whether it has dents or scratches, if the upholstery is worn, whether the servicing is up to date, or if there is any known mechanical issue. These factors can shift the final price by between 10% and 30% compared to the approximate value returned by the valuator. That is why the result of any online valuation by number plate is always a starting reference, not a binding offer.
The tools that allow you to value a car by number plate in Spain
There are several services where you can enter your number plate and obtain an approximate valuation.
Car sales portals such as coches.net, Autocasión or Wallapop have integrated valuators that estimate the vehicle's value based on the registration number and mileage. They are useful for getting a quick reference of the market price on that type of portal, but they do not reflect the price a professional buyer would pay you.

Professional valuation tools like Eurotax or Ganvam are designed for dealerships and assessors. They are more precise than portal valuators because they handle more real transaction data, but full access is not free.
Dealcar's valuator works differently: you enter your registration number and basic car details, and instead of giving you an estimated catalogue price, your vehicle is put in front of more than 1,000 verified professional dealerships making real offers. The result reflects what the market is willing to pay right now for your specific car, not a theoretical estimate.
Why the online valuator result is not the final price
The difference between the value returned by an online valuation tool and the price you actually end up receiving can be significant, and it is worth understanding why before putting a price on your car or negotiating with a buyer.
Portal valuation tools estimate the listing price, not the selling price. The listing price is what the seller asks; the selling price is what they accept at the end of the negotiation. This difference can be 5% to 15% in many cases. If the valuation tool says your car is worth €12,000, that may mean it is advertised at that price, but the sale is completed for between €10,500 and €11,500.
Valuation tools also calculate based on a vehicle in standard condition, without defects or extras. If your car has unrepaired dents, very worn tyres or overdue servicing, the actual price will drop compared to the estimate. If it has relevant extras like a panoramic sunroof, heated seats or a premium sound system, it may go up slightly, although extras usually do not increase the value as much as the owner expects.
Geographical location also has an impact. A diesel SUV is worth more in a rural area where there are fewer driving restrictions than in a city with an active Low Emission Zone (ZBE). Generalist valuation tools do not always capture this local variation accurately.
Also check how the ZBE affects your car's value if you are selling in Madrid.
What data affects the real value beyond the number plate
Mileage is the biggest factor affecting a car's value after the make, model and year. The difference in value between a car with 60,000 km and the same car with 120,000 km can be between €1,500 and €4,000 depending on the model. The more accurate the mileage data you enter into the valuation tool, the tighter the estimate will be.
The condition of the bodywork matters. A car with no visible dents or scratches sells faster and at a better price than one with damage, even if it is minor. Professional buyers discount the cost of repairing any visible damage from the offer they make.
Service history carries weight, especially for cars with more than 80,000 km or older than 5 years. A car with a stamped service book and available maintenance invoices builds more trust and usually receives better offers than one with no documentation.

The environmental badge increasingly affects the value, particularly in cities with traffic restrictions. A vehicle with an ECO or CERO badge is worth more in urban areas than one without a badge or with a C badge, because the buyer knows they can drive without restrictions. The most up-to-date valuation tools already incorporate this factor into their estimates.
How long it takes to do a reliable valuation
A basic valuation by number plate takes less than a minute. You enter the number plate, mileage and general condition of the car, and you immediately obtain an approximate reference.
For a more reliable valuation that reflects the real market price, the complete process with Dealcar takes between 2 and 5 minutes: you add the car's details, upload some photos if you have them, and the system places your vehicle in front of the network of professional buyers. The first real offers arrive on average in less than 18 hours.
This difference between an automatic estimate and a real offer from a professional buyer can be several hundred or even thousands of euros. A car that the online valuator estimates at €11,000 may receive real offers from dealerships ranging from €10,200 to €12,500 depending on the demand for that model at that moment, the specific condition of the car and the interest of each buyer.

Frequently asked questions
Is it reliable to value a car with just the number plate?
The number plate provides the technical details of the vehicle (model, version, registration year), which are the starting point for any valuation. But the actual value also depends on the mileage, the condition of the bodywork and servicing, details that the registration number does not contain. A valuation by number plate alone is approximate; for a real valuation, you also need to provide this information.
Do all online valuation tools give the same result?
No. Each tool uses different data sources and methodologies. Valuation tools on classifieds portals tend to give higher estimates because they are based on asking prices, not closed prices. Professional valuation tools like Eurotax or Ganvam use more real transaction data and are usually more conservative. The difference between one tool and another for the same car can be between €500 and €2,000.
What happens if the online valuation tool gives a price that is very different from what buyers offer me?
This is very common. Online valuation tools give market estimates; actual buyers make concrete offers based on their current demand, the real condition of the car, and what they can resell it for in their area. If the offers you receive are consistently lower than the valuation tool, it may be that the tool is using outdated data or that there are factors affecting the car (condition, high mileage, low-demand model) that lower the actual value.
Can I use the online valuation to negotiate with a dealership?
You can use it as a starting reference, but bear in mind that dealerships are familiar with the same tools and know that online estimates are usually above the actual purchase price. A Dealcar valuation with real offers from professional buyers is a much stronger argument for negotiating than a classifieds portal estimate.
