Frequently asked questions
Before putting your car up for sale, you need a figure. A number you can negotiate with, compare offers against or simply use to decide whether it's worth selling now or waiting. The problem is that this figure is not as easy to determine as it seems.
The value of a used car is not fixed. It depends on the make, model, year, mileage, condition, equipment, time of year and even the geographical area where you sell it. Two cars that are identical on paper can have different market values depending on these factors.
What you can do is get as close as possible to a realistic figure. And for that there are several methods, each with its own advantages and limitations.
Why you need to know your car's value before selling
Selling without a price reference is the most expensive mistake you can make. If you ask too much, your car sits listed for weeks without generating interest. If you ask too little, you sell quickly but leave money on the table.
The problem is that most private sellers set the price intuitively: "I paid X three years ago, so now it'll be worth Y". That logic doesn't work because depreciation is neither linear nor predictable with a rule of thumb. A car that cost 25,000 euros new may be worth 15,000 or 12,000 after three years depending on the model, and the difference between those two figures is huge.
Having a solid reference before selling gives you three concrete advantages. First, you can set a realistic asking price if you publish on listings sites. If you're still not sure where to list it, you can read our analysis of the best site to sell your car in Spain. Second, you can assess whether an offer you receive is good or bad. Third, you can negotiate with data rather than gut feeling.
What factors determine the price of a used car
The value of your car doesn't depend on a single factor, but on the combination of several. Some weigh more than others, but all have an impact.
Make and model. This is the base factor. Some makes hold value much better than others. Toyota models, for example, usually depreciate less than average. Premium brands (BMW, Mercedes, Audi) retain their value if maintenance is documented, but lose more if it isn't.
Year of registration. Each year that passes reduces value, but the curve is not uniform. The biggest drop occurs in the first two years (a new car can lose between 15% and 25% in the first year). From the fourth or fifth year onwards, depreciation eases.
Mileage. The general benchmark in the Spanish market is around 15,000-20,000 km per year. A car with significantly lower mileage than average for its age is perceived as better cared for and holds value better. Above 150,000 km, the discount becomes noticeably steeper.
Overall condition. Dents, scratches, upholstery wear, tyre condition, air conditioning, lights, electronics. Everything adds or subtracts. A car in good cosmetic condition can be worth between 5% and 10% more than a neglected one of the same model and mileage.
Maintenance history. Professional buyers especially value a documented history: service bills, oil changes, timing belt/chain, brakes. A car with a complete history builds trust and justifies a higher price.
Equipment and trim level. Within the same model there can be substantial differences. A basic trim is not worth the same as a fully equipped trim with panoramic roof, reversing camera and driving aids. The most valued extras in the Spanish market are the built-in sat-nav, parking sensors, 360 camera and leather upholstery.
Local market and seasonality. The same car can have different prices in Madrid than in a smaller town. Demand also fluctuates: convertibles sell better in spring, SUVs in autumn, and family cars maintain steady demand all year round.
Methods for calculating how much your car is worth
Consulting listing portals
The most accessible method. You go to Coches.net, AutoScout24 or Wallapop, search for cars of the same model, year and similar mileage, and see what prices they are listed at.
It's a useful reference, but there is an important catch: the asking price is not the selling price. In practice, cars sell for between 5% and 15% below the listed price, after negotiation. If you see your model listed at an average of 14,000 euros, the actual selling price is probably closer to 12,500-13,000 euros.
Another problem: the adverts you see are the ones that haven't sold yet. The cars that sold quickly (probably at a good price) no longer appear, which biases the sample towards cars that have been sitting unsold for a while, often with inflated prices.
Official valuation tables
The Directorate-General for Traffic and the Treasury publish tables with indicative vehicle values. These tables are used mainly to calculate taxes (such as transfer tax on private-party sales), but they do not reflect the real market value.
In most cases, the tax value is lower than the market value. It can serve as a floor reference, but not as a guide for setting a competitive selling price.
Online valuation tools
There are websites and apps that give you an estimate of your car's value by entering make, model, year and mileage. Some of the best known are the Ganvam calculators, AutoScout24 or the tools provided by portals such as Coches.net.
These tools use algorithms based on market data and recent transactions. The estimate is usually reasonably accurate for common cars (mid-range segment, popular makes, standard mileage), but it becomes less reliable for cars with unusual characteristics: uncommon models, special versions, cars with very high or very low mileage.
They are a good first reference, but they should not be your only source.

Receive real offers from professional buyers
This is the most reliable method for knowing the real value of your car. Not the theoretical value, but what someone is willing to pay for it today.
The logic is simple: if three dealerships offer you between 11,500 and 12,200 euros for your car, you know precisely how much it is worth in the professional market right now. No calculator can give you that certainty, because the offer reflects the real demand from specific buyers who know the market.
Platforms such as Dealcar allow you to receive offers from multiple dealerships with no commitment. You upload the car details once and the dealerships interested bid for it. Even if you do not end up selling that way, the offers you receive are the most accurate price reference you can get.
Online valuation vs real offer: why they are not the same
It is a distinction many sellers do not make, and it makes an important difference.
An online valuation is an algorithmic estimate. It is based on statistical data: historical transactions, listed prices and market trends. It is useful as guidance, but it does not take into account the actual condition of your car, the current demand for that model in your area, or the specific condition your vehicle is in.
A real offer, by contrast, is what a specific buyer is willing to pay after learning the characteristics of your car. It is a binding figure (or at least a pre-binding one), not a generic estimate.
The practical difference between the two can be significant. A car that an online tool values at 13,000 euros may receive real offers of 11,500 euros (if the market for that model is weak) or 14,000 euros (if several dealerships need it in stock).
That is why the best strategy is to use the online valuation as a starting point and real offers as confirmation. If both figures match, you have a solid reference. If they differ a lot, trust the real offers more: it is real money on the table.
Common mistakes when valuing your car
Relying only on the purchase price. What you paid for your car does not determine its current value. Depreciation, accumulated mileage and market conditions are what matter.
Adding up the money you've spent. Having changed the tyres or fitted a new sound system does not increase market value. Buyers value the car as a whole, not the workshop invoices.
Comparing with the most expensive advert on the portal. It is tempting to look at the highest listing and think your car is worth the same. But that advert has probably been sitting unsold for weeks precisely because it is overpriced. Look at the average, not the maximum.
Not taking the real condition into account. Small dents, scratches or interior wear that seem "normal" to you can knock hundreds of euros off the buyer's perception. Be honest with yourself when assessing the condition.
Sticking with just one reference. Neither a single online valuation nor a single purchase offer gives you the full picture. Cross-check several sources before setting your price expectation.
Knowing how much your car is worth is not a matter of luck or intuition. It is a matter of cross-checking several sources of information and, above all, getting real offers from buyers who know the market. The more references you have, the more confident you can be that the price you accept is the right one.
Once you know your car's value, the next step is choosing the right channel. We explain how to sell your car quickly and at the best price by comparing all the options.

Frequently asked questions
Are online valuation calculators reliable?
They are a good first reference for common cars. For uncommon models or cars with unusual characteristics they lose accuracy. The most reliable approach is to compare the estimate with real offers from professional buyers.
Is the DGT tax value the market value?
No. The value published by the Treasury or the DGT is an indicative tax value used to calculate taxes such as transfer tax. It is usually lower than the real market value, so it should not be used as a selling reference.
How much does a car depreciate per year?
There is no fixed figure, but as a guide: a typical car loses between 15% and 25% in the first year, 10-15% in the second, and depreciation eases from the third year onwards. After five years, a car may have lost between 40% and 60% of its original value, depending on the make and model.
Do mileage figures matter more than age?
Both factors matter, but in today's Spanish market mileage usually weighs more than age for cars under ten years old. A 5-year-old car with 40,000 km is worth significantly more than one of the same year with 120,000 km.
Can I use Dealcar offers just as a reference without selling?
Yes. Receiving offers on Dealcar does not commit you to anything. You can use them as a market reference and then decide whether to sell that way or through another channel.
