Frequently asked questions

If you're thinking about selling your car, the first thing you need is a number. A price reference that lets you know whether an offer is good, whether you're asking too much or too little, or whether it would make more sense to sell now or wait.
The problem is that the value of a used car doesn't appear anywhere officially and definitively. It's not like checking the price of a share on the stock market. It depends on the make, model, mileage, condition, current demand and even the geographic area. What you can do is get close to a reasonable figure using the tools you have available, 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 combine them to make the best decision.
Why you need to value your car before selling
Selling without a price reference is like negotiating blindfolded. If you only get one offer and have no context, you can't know whether it's fair or whether you're leaving money on the table.
A preliminary valuation helps you in three concrete ways. First, set a realistic asking price if you decide to list your car on an advertising portal. Second, assess whether the offers you receive are in line with the market. This is especially important if you're considering selling to a direct-buy company, where you only receive one offer. Third, negotiate with arguments when someone makes you a counteroffer.
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 right or it might be €2,000 away from reality, and the difference between the two scenarios is significant.
Dealcar: value your car for free and receive offers from dealerships
Dealcar provides a free valuer that values your car in less than 30 seconds. You enter the registration plate and vehicle details, and receive a valuation based on real closed-sale prices in the market, not catalogue estimates.
From there, your car is presented to a network of more than 1,000 verified professional dealers who bid against each other to buy it. On average, the first offers arrive in less than 18 hours. You compare them and keep the best one. If none suits you, you turn them down with no penalty.
What sets Dealcar apart from the rest:
100% free for you. No commissions or hidden costs. The buyers pay to access your car; you pay nothing.
You get paid before handing over the keys. The money reaches your account by bank transfer before you hand over the car.
They collect your car from your home. The buying company takes care of collecting it wherever you say. You don't have to travel.
No paperwork. The buyer handles the transfer, the notification to the DGT and all the admin.
On average, €1,400 more than selling on Wallapop. Competition between professional buyers naturally drives the price up.
More than 12,000 cars sold and an average rating of 4.9 out of 5 back the model.
If you want to know how much your car is worth today, use Dealcar's free valuer.
Other tools for valuing your car online
There are several options on the Spanish market that let you get an estimate at no cost. Each uses different sources and methods, so it's worth knowing about them.
Classifieds sites as a reference
It's not a valuation tool as such, but it's the method most people use. You go to Coches.net, AutoScout24 or Wallapop, search for cars similar to yours (same model, year, approximate mileage) and see what price they're listed at.
It's a quick and accessible reference, but it has an important bias: you're seeing asking prices, not sale prices. The cars that appear are the ones that haven't sold yet, many of them because they're overpriced. The ones that sold quickly (probably at a good price) are no longer there. In addition, the final sale price is usually between 5% and 15% lower than the listed price, after negotiation.
As a rough reference it works. As a figure for making decisions, it needs to be supplemented.
Ganvam valuation tables
Ganvam (National Association of Motor Vehicle Sellers) publishes valuation tables quarterly based on real transactions in the professional market. It's one of the most reliable sources because it reflects actual sale prices, not listing prices.
The tables are available online and free of charge. The limitation is that they don't cover every version and trim level of each model, so the estimate can be generic if your car has a specific configuration.
Tax tables from the Spanish Treasury
The Ministry of Finance publishes annual tables with the fiscal value of used vehicles. These tables are used to calculate taxes such as ITP (Property Transfer Tax), which applies to private sales.
It's important to understand that the fiscal value is not the market value. In most cases, the Treasury tables give figures below the real price at which you could sell your car. They serve as a reference floor (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 insurers' tools that estimate replacement value. Some are free, others require registration.
Reliability varies a great deal from one to another. Those based on real 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 car's new sale price in the corresponding version and trim. From there, discounts are applied for age (each year subtracts a percentage), for mileage (compared with 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 incorporate, the more accurate the estimate.
What no calculator can do is assess the actual condition of your specific car. Scratches, upholstery wear, maintenance history or whether the air conditioning works properly. Those factors are only captured in a physical inspection or when a professional buyer assesses the vehicle.

What data you need to value your car
To get the most accurate valuation possible, have the following information to hand before using any tool.
Make and exact model. A Seat León Style is not the same as a Seat León FR. The version and trim directly affect the price.
First registration date. Not the model year, but when it was first registered. That's the data tools and buyers use.
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 market value, where demand for diesel has fallen and demand for hybrids and automatics has risen.
Notable equipment. Built-in navigation, panoramic roof, parking sensors, 360 camera, leather upholstery, LED headlights. Factory or added extras can add to the value, although not as much as most sellers think.
General condition. Dents, scratches, tyre condition, repair history. Online calculators don't usually ask for this detail, but it's the factor that makes the biggest difference between the online estimate and the real 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 worth knowing so you don't make decisions based on incomplete data.
They don't value 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 damage, interior wear or mechanical problems. Calculators don't capture that difference.
They lose accuracy on unusual cars. Uncommon models, special editions, cars with many or very few kilometres for their age, or vehicles with an import history don't 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, closed listing prices). If the market is changing quickly (for example, a rise in demand for hybrids or a fall in demand for diesel), the estimate can become out of date.
Each tool gives a different number. It is common for the Coches.net valuation, the AutoScout24 one and the Ganvam one to differ by 5-15%. This doesn't mean one is right and the others wrong, but that each uses different sources and methods. Reality is usually somewhere in the middle.
Once you know 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 compare several sources and not rely on a single figure.
Step 1: Check at least two online tools. Use the Coches.net calculator and the AutoScout24 one at a minimum. If you can, also check Ganvam's 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. Focus on the average, not the most expensive or the cheapest. And remember that the real sale price is 5-15% lower than the listed price.
Step 3: Use Dealcar's free valuer and receive real offers. This is the step that turns an estimate into certainty. Dealcar's valuer lets you enter your car's details (make, model, version, mileage, environmental label, colour and province) and get a valuation based on real market data. The process takes less than two minutes and costs nothing.
But the most interesting part comes afterwards: once the valuation is complete, your car is presented to more than 1,000 professional dealers that can send you real offers. When a dealer says "I'll pay you €12,500 for your car", that number is not an algorithmic estimate: it's 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 don't end up selling that way, the combination of the initial valuation and the dealership offers gives you a much firmer 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're a good rough reference, especially for popular models with standard mileage. For unusual cars or those with special features they lose accuracy. The most reliable approach is to compare several sources and complement them with real offers from buyers.
Which is the best tool to value my car for free?
There isn't one single tool that's best for every case. The Coches.net and AutoScout24 calculators are good for an initial guide. Ganvam's tables reflect real transaction prices. But if you want the most accurate reference, Dealcar's free valuer combines an initial valuation with real offers from professional dealerships, which is the closest thing to the real market price.
Does the value in the Treasury tables equal the market value?
No. Tax tables are used to calculate taxes and usually give values below the real market. You shouldn't use them as a reference for setting a sale price.
How much does a car depreciate per year?
As a general guide, an average car loses between 15% and 25% in the first year. Depreciation slows from the third year onwards. After five years, a car may have lost between 40% and 60% of its original value, depending on 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: navigation, parking sensors, rear camera, automatic gearbox. Purely aesthetic extras (special wheels, decals, ambient lighting) have very little impact on the price.
