The best portals for selling used cars in Spain

1. Coches.net

The portal with the largest volume of specialist 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 advert options and the ability to integrate directly with stock management systems such as Dealcar. Buyers who arrive here are usually at an advanced stage of decision-making, which translates into higher-quality leads.

What to bear in mind: competition is high. If you don't take care over the photos, price and description, your advert gets lost among hundreds of similar options. Subscription and featured listing costs can rise quickly if you don't keep control of lead return.

2. AutoScout24

A benchmark in Europe, with a strong presence in Spain and especially interesting if you work with mid-to-high-end or imported vehicles.

What works well: real 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 buyers compare prices quickly.

What to bear in mind: in Spain, its market share is smaller than Coches.net's. For budget cars or very local stock, it may not be the best investment as a single channel.

3. Wallapop

What began as a general second-hand portal has become a relevant channel for car sales, especially in lower and mid-price segments.

What works well: massive volume of daily active users, especially on mobile. The Wallapop buyer is looking for immediacy and geographical proximity, which favours local dealerships. Listing is free in its basic version, although featured options are paid.

What to bear in mind: the buyer profile is usually more price-sensitive and less loyal. In addition, the platform is not specifically designed for motor trade professionals, which can make management difficult if you handle a large stock.

4. Milanuncios

Another generalist portal with a very popular motor section in Spain. Its strength lies in its established user base and SEO positioning.

What works well: large volume of organic traffic, especially in searches such as "cheap used car" or "used cars [city]". A good option for fast-turnover cars and competitive prices.

What to bear in mind: the listing experience for professionals is not as polished as on specialist portals. And, like Wallapop, the buyer tends to negotiate on price more aggressively.

5. Facebook Marketplace

It's not really a car portal as such, but its volume of users makes it a channel that many dealerships already use, especially for attracting local buyers.

What works well: organic reach in your area, the ability to combine it with targeted advertising on Facebook and Instagram, and direct contact via Messenger. For mid-to-low-priced cars, it can generate quick enquiries.

What to bear in mind: there is no professional integration with stock management systems, management is manual and the lead quality is uneven. It requires dedication and does not replace specialist portals.

5. Autocasión

A specialist portal from the Vocento group, with an established audience and editorial focus that builds trust with the buyer.

What works well: good Google ranking for informational searches about used cars. The buyer who arrives at Autocasión has usually done quite a bit of research beforehand, which can translate into better-qualified leads.

What to bear in mind: lower traffic volume than Coches.net or Wallapop. It works better as a complementary channel than as the main source of leads.

Google Vehicle Ads: the channel many dealerships ignore

Alongside the classic portals, there is a channel that is gaining ground and that many independent dealerships still don't 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 search, not inside a marketplace where there are dozens of similar adverts. For dealerships that already have their stock digitised, activating Google Vehicle Ads can be a major boost in visibility without relying exclusively on portals. If you want to go deeper into how to set it up and what results you can expect, we recommend our complete Google Vehicle Ads guide for dealerships.

Beyond portals: new ways to source stock and buyers

Listing on portals solves part of the equation: giving visibility to the cars you already have in stock. But there is another part that is just as important and that many dealerships are still solving in an artisanal way: where do the cars you sell come from?

Most independent dealers buy from private sellers (on Wallapop, Milanuncios or via 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's why at Dealcar we created DealConnect, which allows dealerships to access a marketplace with three sourcing channels in one place:

Dealer network: access the stock of other dealerships in the network at trade price. You can even offer a car to your customer before buying it, reducing the risk of dead stock.

Private seller channel: private sellers who want to sell their car value it directly on the dealership website. The dealer receives the opportunity with 24 hours of exclusivity before it is shared with the rest of the network. This turns the dealership website into an active stock sourcing channel, not just a sales channel.

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 each opportunity comes with estimated margin data, market price and turnover speed in your area. You are not buying blind: you are buying what makes you money.

How to manage listings across multiple 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: out-of-date adverts, inconsistent prices between portals and wasted time you could spend helping customers or closing sales.

The solution is to centralise stock management in a single system that synchronises automatically with all portals. You upload the car once, choose which portals you want to list it on and the system takes care of the rest. If you change the price or mark the car as sold, it is updated everywhere.

This not only saves time (between 5 and 10 hours a week in many cases), but also allows you to measure which portal generates more visits, more leads and more real sales. Without that information, it's impossible to know whether you're investing well. If you want to see how automatic portal listings work, we explain it in detail in our article on how to list your cars on multiple portals effortlessly.

Another factor that makes a difference on portals is photo quality. An advert with professional images gets significantly more clicks than one with dark or blurry photos. AI image enhancement tools can turn mobile phone photos into professional-looking images in seconds. If you're interested, you can see how Dealcar's AI photo enhancement works.

Conclusion

Choosing the right portals is still an important decision for any used car dealership. But the winning strategy is no longer simply being everywhere; it's combining portal visibility with your own sourcing channels, measuring what works and automating everything that can be automated so you can spend your time on what drives the business: buying well and selling better.

Frequently asked questions

What is the best portal for selling used cars in Spain?

There isn't just 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 gives you the best return. It depends on the type of car, your area and your buyer profile.

Is it worth listing on generalist portals like Wallapop or Milanuncios?

Yes, especially for low and mid-priced cars with high turnover. Buyers on these portals are more price-sensitive, but the user volume makes up for it. The key is not to rely on them exclusively.

What is DealConnect and how does it differ from a portal?

DealConnect is not a public-facing sales portal. It's a stock sourcing marketplace for dealerships, exclusive to Dealcar customers, 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 list on all portals at once without doing it manually?

Yes. With multipublishing tools like Dealcar's, you upload the car once and it is published automatically on Coches.net, AutoScout24, Wallapop, your website and other portals. Any changes are synchronised in real time.

Does Google Vehicle Ads replace portals?

No, but it complements them very powerfully. It lets you appear directly in Google searches with your stock, without relying on an intermediary. For dealerships with digitised stock, it is a channel with a very good visibility-to-cost ratio.

More than 750 dealerships already use Dealcar
