The best portals to sell second-hand cars in Spain
1. Coches.net
The portal with the highest volume of specialised automotive traffic in Spain. For professional dealerships, it remains the main lead generation channel.
What works well: a very comprehensive filter system for the buyer, high organic visibility on Google, featured advertisement options, and the possibility of direct integration with stock management tools like Dealcar. Buyers arriving here are usually in an advanced stage of decision-making, which translates into higher quality leads.
What to keep in mind: competition is high. If you do not look after photos, price and description, your ad will get lost among hundreds of similar options. Subscription and featured listing costs can rise quickly if you do not control the return per lead.
2. AutoScout24
A reference in Europe, with a strong presence in Spain and particularly interesting if you work with mid-to-high-range or imported vehicles.
What works well: genuine international reach. If your dealership is in tourist or border areas, this portal can attract buyers from other countries. The interface is clean and the vehicle valuation system helps the buyer compare prices quickly.
What to keep in mind: in Spain, its market share is lower than that of Coches.net. For budget cars or those with a very local profile, it may not be the best investment as a sole channel.
3. Wallapop
What started as a generalist second-hand portal has become a relevant channel for selling cars, especially in low and medium price segments.
What works well: massive volume of daily active users, especially on mobile. The Wallapop buyer seeks immediacy and geographical proximity, which favours local dealerships. Publishing is free in its basic version, although featured options are paid.
What to keep in mind: the buyer profile is usually more price-sensitive and harder to retain. Furthermore, the platform is not designed specifically for automotive professionals, which can make management difficult if you handle a large stock.
4. Milanuncios
Another generalist with a highly used motor section in Spain. Its strength lies in its consolidated user base and its SEO positioning.
What works well: high volume of organic traffic, especially in searches like "cheap second hand car" or "used cars [city]". Good option for fast-turnover cars and competitive prices.
What to keep in mind: the publishing experience for professionals is not as polished as in specialised portals. And just like Wallapop, the buyer tends to negotiate the price more.
5. Facebook Marketplace
It is not a car portal as such, but its volume of users makes it a channel that many dealerships already use, especially to attract local buyers.
What works well: organic reach in your area, possibility of combining with targeted advertising on Facebook and Instagram, and direct contact via Messenger. For medium-low priced cars, it can generate quick contacts.
What to keep in mind: there is no professional integration with stock management tools, management is manual, and the quality of leads is uneven. It requires dedication and does not replace specialised portals.
6. Autocasión
Specialised portal of the Vocento group, with a consolidated audience and editorial focus that builds buyer trust.
What works well: good positioning on Google for informative searches about used cars. The buyer who reaches Autocasión has usually researched quite a lot beforehand, which can translate into more qualified leads.
What to keep in mind: lower traffic volume than Coches.net or Wallapop. It works better as a complementary channel than as a main source of leads.

Google Vehicle Ads: the channel many dealerships ignore
In addition to the classic portals, there is a channel that is gaining ground and that many independent dealerships still do not take advantage of: Google Vehicle Ads (formerly Vehicle Listing Ads).
This format allows your cars to appear directly in Google search results with a photo, price, mileage and location. The buyer sees your car before entering any portal.
The main advantage is that you compete directly in the search, not within a marketplace where there are dozens of similar ads. For dealerships that already have their stock digitised, activating Google Vehicle Ads can be a significant leap in visibility without relying exclusively on portals. If you want to dive deeper into how to set it up and what results you can expect, we recommend our complete guide to Google Vehicle Ads for dealerships.
DealConnect: Beyond portals, new ways to acquire stock and buyers
Publishing on portals solves one part of the equation: giving visibility to the cars you already have in stock. But there is another equally important part that many dealerships still solve in a traditional way: where do the cars you sell come from?
Most independent dealers buy from individuals (on Wallapop, Milanuncios or cold calling), at auctions or from other dealerships. The problem is that each channel requires time, negotiation and a different process.
This is where the model is evolving. That is why at Dealcar we have created DealConnect, which allows dealerships to access a marketplace with three sourcing channels in one single place:
Dealer Network: you access the stock of other dealerships in the network at professional prices. You can even offer a car to your customer before buying it, reducing the risk of stagnant stock.
Private Seller Channel: private individuals who want to sell their car value it directly on the dealership's website. The dealer receives the lead with 24-hour exclusivity before it is shared with the rest of the network. This turns the dealership's website into an active stock acquisition channel, not just a sales one.
Remarketing Channel: direct access to auctions, fleets and exclusive agreements with operators such as Autorola, BCA or Auto1. Opportunities that do not appear on open portals.
The interesting thing about this model is that every opportunity comes with estimated margin data, market price and turnover speed in your area. You do not buy blindly: you buy what makes you money.

How to manage publishing on several portals without losing control
Being on five portals at once sounds good, but managing it manually is a real problem. Uploading the same car to Coches.net, AutoScout24, Wallapop and your website means repeating photos, descriptions and prices several times. And when you sell the car, you have to remember to remove it from all of them.
The usual result: outdated ads, inconsistent prices across portals and wasted time that you could spend assisting clients or closing sales.

The solution lies in centralising stock management into a single system that synchronises automatically with all portals. You upload the car once, define which portals you want to publish it on, and the system handles the rest. If you change the price or mark the car as sold, it updates everywhere.
This not only saves time (between 5 and 10 hours a week in many cases), but it allows you to measure which portal generates the most visits, the most leads and the most actual sales. Without that information, it is impossible to know if you are investing well. If you want to see how automatic publishing on portals works, we explain it in detail in our article on how to publish your cars on multiple portals effortlessly.
Another aspect that makes a difference in portals is photo quality. An ad with professional images receives significantly more clicks than one with dark or blurry photos. IA-powered image enhancement tools allow you to convert photos taken with a mobile phone into professional-looking images in seconds.

Conclusion
Choosing the right portals remains an important decision for any second-hand dealership. But the winning strategy is no longer simply to be in many places, but to combine visibility on portals with your own acquisition channels, measure what works, and automate as much as possible to spend time on what moves the business: buying well and selling better.

Frequently asked questions
What is the best portal to sell used cars in Spain?
There is no single one. Coches.net is the benchmark for traffic volume and lead quality, but the most effective strategy is to combine several portals and measure which one generates the best return for you. It depends on the type of car, your area and your buyer profile.
Is it worth publishing on generalist portals like Wallapop or Milanuncios?
Yes, especially for low and medium priced cars with high turnover. The buyer on these portals is more price-sensitive, but the volume of users makes up for it. The key is not to rely exclusively on them.
What is DealConnect and how does it differ from a portal?
DealConnect is not a public sales portal. It is a sourcing marketplace for dealerships exclusive to Dealcar clients where you can find cars from other dealers, private sellers and auctions, with margin and turnover data. It helps you buy better, not just sell.
Can I publish on all portals at once without doing it manually?
Yes. With multi-publishing tools like Dealcar's, you upload the car once and it is automatically published on Coches.net, AutoScout24, Wallapop, your website and other portals. Any change is synchronised in real time.
Does Google Vehicle Ads replace portals?
It does not replace them, but it complements them very powerfully. It allows you to appear directly in Google searches with your stock, without depending on an intermediary. For dealerships with digitised stock, it is a channel with a very good visibility/cost ratio.
