How lead generation works on a car portal
A car portal such as Coches.net, AutoScout24 or Wallapop is a marketplace: the buyer arrives, filters by their criteria (make, model, price, mileage, area) and sees the available cars from various dealerships in the same showcase. If they are interested in one, they click and contact the dealership.
The logic of generation on a portal is that of visible competition: the dealership competes on price, photo quality, completeness of the listing and response time, all within the same environment used by the competition. The buyer who arrives already knows more or less what they are looking for: they have defined their filters before seeing the results.
The business model of portals for dealerships is usually a monthly subscription (by exposure level, number of published cars or position in the results) plus, in some cases, payment per lead generated. The dealership pays to be present in the showcase, not for each click received.

How lead generation works in ChatGPT Ads
ChatGPT Ads is not a marketplace. There is no catalogue where the buyer filters and compares cars from several dealerships at the same time. The ads appear in the context of a conversation where the buyer is asking for advice or help to define what car they need.
The logic of generation is that of contextual relevance: the ad appears because OpenAI's system has determined that the advertised car is relevant to the conversation the buyer is having. There is no shared showcase with the competition in the same format: there may be only one ad visible, or there may be none at all if the system does not consider the ad to be sufficiently relevant.
The business model is pay-per-click or pay-per-impression: the dealership pays for each interaction, not for being in a catalogue. The cost depends on the bid and the relevance of the ad to the conversation where it appears.
See the complete guide to ChatGPT Ads for dealerships.
The stage of the buying process captured by each channel
This is the most important difference and the one that justifies treating the two channels as complementary.
The portal captures the buyer in the active comparison phase. The buyer has already decided they want to buy a used car, already knows approximately what type they are looking for and is evaluating the options available now. It is an advanced stage in the decision-making process, with high and specific intent.

ChatGPT Ads can capture the buyer at an earlier stage: when they are still defining what car they need, comparing vehicle types, evaluating whether to buy new or used, or seeking advice on what features to prioritise within their budget. It is an earlier stage in the process, with high but less specific intent regarding the concrete car.
The same buyer can go through both channels in their buying process: first they ask ChatGPT for guidance, then they enter a portal to compare specific options. If the dealership has a presence in both channels, it can appear at both stages of the process.
Where the dealership competes in each channel
On a portal, the dealership competes directly with other dealerships that have similar cars. The buyer sees the results filtered by their criteria and compares price, photos and description among several options at the same time. The dealership with the most adjusted price, the best photos or the most complete description has an advantage within that shared showcase.
In ChatGPT Ads, the dealership's ad may be the only one that appears in that specific conversation. There is no shared showcase in the same format: the buyer is not comparing three ads from different dealerships on the same screen. The click or the decision not to click is made on that ad in a more isolated way.
This has different consequences for the pricing and presentation strategy. On the portal, the price has to be competitive compared to similar cars in the same showcase. In ChatGPT Ads, the price is still important, but the context of direct comparison does not exist in the same way.
The difference in intent between the portal buyer and the ChatGPT buyer
The buyer coming from a portal has applied filters: they know they want a car between €10,000 and €15,000, diesel, with less than 100,000 km, in Madrid. They have narrowed their search down to a set of options and are evaluating which is the best.
The buyer clicking on a ChatGPT Ads ad arrives with more narrative context: they have been describing their situation to the AI, have received a recommendation and have clicked on the car that fits that recommendation. They have more information on why that specific car might be good for them.
This difference in context can translate into a difference in lead quality. A buyer coming from ChatGPT Ads having had a conversation where the AI explained why that car fits their needs may have more certainty about what they are looking for and less friction in decision-making. Or they may be at an earlier stage in the process and need more follow-up before committing to a visit.
Specific data for the Spanish automotive market on ChatGPT Ads is still scarce because the channel has just opened. The way to know for sure is to measure the conversion rate from lead to visit and from visit to sale by channel in your own business.
Cost per lead: what to expect from each channel
The cost per lead on portals varies greatly depending on the portal, the contracted level of exposure and the type of stock. As an approximate guide, the cost per lead on generalist used car portals in Spain is in a range of between €3 and €15 per lead, depending on the car's profile and the subscription level.
The cost per lead in ChatGPT Ads does not yet have an established benchmark for automotive in Spain. With a CPC of between €3 and €5 (OpenAI's recommended bid) and a click-to-lead conversion rate of between 5% and 15% depending on the sector and landing page quality, the estimated cost per lead would be in a range of between €20 and €100. That range is higher than that of the portals, but the context of the conversation can justify it if the quality of the lead is higher.

The correct comparison is not the cost per lead but the cost per sale. If ChatGPT Ads leads have a higher close rate than portal leads, the cost per sale can be comparable or lower even if the cost per lead is higher.
Coches.net is already on ChatGPT: what changes for the independent dealership
In May 2026, Coches.net announced the integration of its vehicle selection into ChatGPT, becoming the first mobility marketplace in Spain to do so. This means that cars published on Coches.net can appear in ChatGPT's organic responses when someone asks about available cars.
This integration is relevant for dealerships that already publish on Coches.net: their cars can appear on ChatGPT through the portal, at no additional cost per click.
The first is that this visibility is organic, not guaranteed. ChatGPT does not show all the cars from the portal in every relevant conversation: it shows those that the system considers most relevant to that specific conversation. The dealership does not control when and how its stock appears in those responses.
The second is that ChatGPT Ads ads appear in a different block to the organic results. A dealership paying for ChatGPT Ads has guaranteed visibility in the ad block; one that only publishes on Coches.net has potential visibility in organic results but with no guarantee or control.
The third is that Coches.net's integration with ChatGPT benefits all advertisers on the portal equally in terms of eligibility, which means that the independent dealership competes with large car groups in that organic channel just as it does on the portal.
Why they are not substitutes
The most frequent argument when a new channel is launched is whether it replaces the previous one. ChatGPT Ads does not replace portals for three structural reasons.
The first is volume: portals have millions of active users with decades of established search habits. ChatGPT has tens of millions of global users but the habit of searching for specific cars on ChatGPT is still forming in Spain.
The second is the stage of the process: portals are irreplaceable in the active comparison phase where the buyer evaluates specific options. ChatGPT may be more relevant in the prior guidance phase, but it does not replace the need to see available options with price and photo in a catalogue.
The third is infrastructure: portals have car valuation systems, finance calculators, new ad alerts, dealership profiles with reviews and a whole user experience built specifically for buying cars. ChatGPT Ads is an advertising channel, not a complete buying platform.
The combined strategy: how to integrate both into the same funnel
The strongest strategy for a dealership that wants to maximise lead generation is to treat the two channels as complementary and design the sales funnel keeping in mind that the same buyer can appear in both.
A presence on portals ensures visibility in the active comparison phase. A presence on ChatGPT Ads adds visibility in the prior guidance phase. A buyer who sees the dealership's ad on ChatGPT and clicks arrives at the car's listing on the dealership's website. If that buyer later searches on Coches.net, they see the same car again. This repetition of impressions reinforces the decision.
For the combined strategy to work, both channels have to lead to the same destination: the vehicle's listing on the dealership's website, with quality photos, the full description and the contact form visible. A dealership without its own website featuring individual car listings loses consistency between channels and the ability to correctly measure the origin of each lead.

Dealcar and visibility in both channels
Dealcar manages stock publishing on the main car portals (Coches.net, AutoScout24, Wallapop and others) from a single panel, with automatic synchronisation when a car is sold. Dealcar is developing the integration of stock with ChatGPT Ads so that the same inventory published on portals also feeds the ChatGPT Ads product feed with no extra work.

Frequently Asked Questions
If I already publish on Coches.net and Coches.net is integrated with ChatGPT, do I need ChatGPT Ads?
They are different things. Coches.net's integration with ChatGPT provides organic visibility: your cars can appear in ChatGPT's answers, but with no guarantee or control over when and how. ChatGPT Ads provides guaranteed visibility in the ad block when the system considers the ad relevant to the conversation. They are complementary, not equivalent.
Does it make sense to reduce the portal budget to invest it in ChatGPT Ads?
Not at first. Portals are established channels with known volume and benchmarking. ChatGPT Ads is a new channel in beta. The recommended strategy is to test ChatGPT Ads with an incremental budget (€200-300 per month) without reducing portal presence, and adjust the distribution when you have your own data on each channel's performance.
Can the same lead come from both a portal and ChatGPT Ads?
Yes. The same buyer may have been influenced by the ChatGPT Ads ad and later contacted through the portal. Without measuring the lead source in the CRM, this influence is invisible. The post-conversion survey ("how did you find us?") is the most direct way to capture these multi-channel interactions.
