Frequently asked questions
If you are thinking of selling your car, the first thing you need is a figure. A price reference that lets you know if an offer is good, if you are asking too much or too little, or if it is directly worth selling now or waiting.
The problem is that the value of a used car does not appear anywhere officially and definitively. It is not like checking the price of a stock on the stock exchange. It depends on the make, model, mileage, condition, current demand and even the geographical area. What you can do is get close to a reasonable figure using the tools available to you, and most of them are free.
In this article we explain how to value your car online for free, what tools exist, how reliable they are and how to supplement them to make the best decision.
Why you need to value your car before selling
Selling without a price reference is like negotiating with your eyes closed. If you only receive one offer and have no context, you cannot know if it is fair or if you are leaving money on the table.
A prior valuation serves three specific purposes. First, to set a realistic starting price if you decide to list your car on a classifieds portal. Second, to assess whether the offers you receive are in line with the market. This is especially important if you are considering selling to an instant car buying company, where you only receive one offer. Third, to negotiate with arguments when someone makes you a counter-offer.
The most common mistake is to skip this step and rely on intuition. "I paid 18,000 four years ago, so now it must be worth about 12,000." That estimate might be fine or it might be 2,000 euros off reality, and the difference between both scenarios is significant.
Dealcar: value your car for free and receive offers from dealerships
Dealcar offers you a free valuation tool that values your car in less than 30 seconds. You enter the registration plate and the vehicle details, and you receive a valuation based on real closed sales prices in the market, not catalogue estimates.
From there, your car is presented to a network of over 1,000 professional and verified dealerships that bid against each other to buy it. On average, the first offers arrive in less than 18 hours. You compare and keep the best one. If none of them convince you, you reject it without any penalty.
What sets Dealcar apart from the rest:
100% free for you. No commissions or hidden costs. Dealerships pay to access your car, you pay nothing.
You get paid before handing over the keys. The payment arrives in your account via bank transfer before you hand over the car.
Home collection of the car. The buying dealership takes care of collecting it wherever you say. You do not have to travel.
No paperwork. The dealership manages the transfer, notification to the DGT (Traffic Authority) and all the paperwork.
On average, 1,400 euros more than selling on Wallapop. Competition between professional buyers naturally drives up the price.
More than 12,000 cars sold and an average rating of 4.9 out of 5 back up the model.
If you want to know how much your car is worth today, use Dealcar's free valuation tool.
Other tools to value your car online
There are several options in the Spanish market that allow you to get an estimate at no cost. Each uses different sources and methods, so it is useful to know them.
Classifieds portals as a reference
It is not a valuation tool as such, but it is the method most people use. You go onto Coches.net, AutoScout24 or Wallapop, look for cars similar to yours (same model, year, approximate mileage) and see what price they are listed at.
It is a quick and accessible reference, but it has a significant bias: you are seeing listing prices, not selling prices. The cars that appear are the ones that have not been sold yet, many of them because they are overpriced. The ones that sold quickly (probably at a good price) are no longer there. In addition, the final selling price is usually between 5% and 15% lower than the listed one, after negotiation.
As a rough guide, it works. As data to make decisions, it needs to be supplemented.
Ganvam valuation tables
Ganvam (National Association of Motor Vehicle Dealers) publishes quarterly valuation tables based on real transactions in the professional market. It is one of the most reliable sources because it reflects actual trade-in prices, not listing prices.
The tables are available online and are free. The limitation is that they do not cover all versions and equipment of each model, so the estimate can be generic if your car has a specific configuration.
Hacienda tax tables
The Ministry of Finance (Hacienda) publishes annual tables with the tax value of used vehicles. These tables are used to calculate taxes such as the ITP (Property Transfer Tax), which applies to sales between private individuals.
It is important to understand that the tax value is not the market value. In most cases, Hacienda's tables give figures lower than the real price you could sell your car for. They serve as a floor reference (your car is worth at least this much), but not as a ceiling.
Independent apps and tools
There are several apps and websites that offer free valuations, such as Eurotax (now integrated into professional platforms) or insurance company tools that estimate replacement value. Some are free, others require registration.
Reliability varies greatly from one to another. Those based on actual transaction data are more accurate than those that only use generic statistical models.
How valuation calculators work
All online valuation tools work on the same basic principle: they apply a depreciation model to a base value, adjusted by variables.
The base value is usually the retail price of the new car in its corresponding version and equipment. From there, discounts are applied for age (each year subtracts a percentage), for mileage (compared to the expected average for that age) and for general condition (if the tool allows it).
Some more sophisticated calculators incorporate real-time market data: what price similar cars are selling for on portals, how many are available (supply) and how many searches they receive (demand). The more variables they integrate, the more accurate the estimate.
What no calculator can do is assess the actual condition of your specific car. Scratches, wear and tear on the upholstery, service history or whether the air conditioning works properly. Those factors are only captured in a physical inspection or when a professional buyer evaluates the vehicle.
What information you need to value your car
To get the most accurate valuation possible, have the following information to hand before using any tool.
Exact make and model. A Seat León Style is not the same as a Seat León FR. The version and trim directly influence the price.
Year of first registration. Not the model year, but when it was first registered. This is the detail used by tools and buyers.
Current mileage. The more precise, the better. The difference between 80,000 km and 95,000 km can be hundreds of euros in the valuation.
Fuel type and gearbox. Diesel, petrol, hybrid or electric. Manual or automatic. These are variables that significantly affect value in today's market, where demand for diesel has fallen and that for hybrids and automatics has risen.
Key features. Built-in sat nav, panoramic roof, parking sensors, 360 camera, leather upholstery, LED headlights. Standard or added extras can add to the value, although not as much as most sellers believe.
General condition. Dents, scratches, tyre condition, repair history. Online calculators do not usually ask for this detail, but it is the factor that generates the most difference between the online estimate and the actual price a buyer is willing to pay.
If in addition to the valuation you want to get everything ready for the sale, check the documents needed to sell your car.
Limitations of online valuations
Online valuation tools are useful as a starting point, but they have limitations that are worth knowing so as not to make decisions based on incomplete data.
They do not assess the actual condition of your car. Two cars of the same model, year and mileage can have very different values if one is immaculate and the other has dents, interior wear or mechanical problems. Calculators do not capture that difference.
They lose accuracy with unusual cars. Uncommon models, special editions, cars with very high or very low mileage for their age, or vehicles with an import history do not fit well into standard statistical models.
They reflect the past, not the present. Many tools base their estimates on historical data (transactions from previous months, prices of already closed listings). If the market is changing fast (for example, a surge in demand for hybrids or a drop in demand for diesel), the estimate may become outdated.
Every tool gives a different number. It is common for the valuation from Coches.net, AutoScout24 and Ganvam to differ from each other by 5-15%. This does not mean that one is right and the others wrong, but rather that each uses different sources and methods. The reality is usually somewhere in between.
Once you are clear on the value, the next step is to choose where and how to sell. We explain the options in how to sell your car quickly and at the best price.
How to get the most reliable value for your car
The most sensible strategy is to cross-reference several sources and not stick to a single figure.
Step 1: Consult at least two online tools. Use the Coches.net calculator and the AutoScout24 one at the very least. If you can, also consult the Ganvam tables. Note down the price range they give you.
Step 2: Check listings for similar cars. Search portals to see how many cars like yours are for sale and at what price. Look at the average, not the most expensive or the cheapest. And remember that the actual selling price is 5-15% lower than the listed one.
Step 3: Use Dealcar's free valuation tool and receive real offers. This is the step that turns the estimate into certainty. Dealcar's valuation tool allows you to enter your car's details (make, model, version, mileage, environmental badge, colour and province) and get a valuation based on real market data. The process takes less than two minutes and has no cost.
But the most interesting part comes next: once the valuation is complete, your car is presented to more than 1,000 professional dealerships that can send you real offers. When a dealership tells you "I will pay you 12,500 euros for your car", that number is not an algorithmic estimate: it is real money on the table. If you receive three or four offers from different dealerships, you have the most accurate picture possible of your car's value today.
Even if you do not end up selling that way, the combination of the initial valuation and the dealership offers gives you a much more solid price reference than any generic calculator, because it reflects what professional buyers are willing to pay today, for your specific car, in the current market.
Frequently asked questions
Are online valuations reliable?
They are a good rough guide, especially for popular car models with standard mileage. For unusual cars or those with special features, they lose accuracy. The most reliable approach is to cross-reference several sources and supplement with real offers from buyers.
What is the best tool to value my car for free?
There is no single one that is best for all cases. The calculators on Coches.net and AutoScout24 are good for an initial orientation. The Ganvam tables reflect real transaction prices. But if you want the most accurate reference, Dealcar's free valuation tool combines an initial valuation with real offers from professional dealerships, which is the closest thing to the real market price.
Is the value in Hacienda's tables the market value?
No. The tax tables are used to calculate taxes and usually give values below the real market. You should not use them as a reference to set a selling price.
How much does a car depreciate per year?
As a general guide, an average car loses between 15% and 25% in its first year. Depreciation slows down from the third year onwards. By five years, a car may have lost between 40% and 60% of its original value, depending on the make and model.
Do car extras add value to the valuation?
Yes, but less than most sellers expect. The extras most valued by the market are those that add practical functionality: sat nav, parking sensors, rear camera, automatic gearbox. Purely aesthetic extras (special alloys, decals, ambient lighting) barely influence the price.
