Trilingual AI Dealership Platform
A used-car dealership in Castello de la Plana, Spain: a complete production system, a trilingual website, a voice and text AI assistant, self-serve inventory, and a local SEO/AEO engine, designed, built, and run end to end.
The challenge
A local dealer was selling slowly with almost no online presence. Buyers could not find the stock, and the ones who did had no easy way to ask about a car outside opening hours.
The customer base was mixed, with a large Romanian-speaking community alongside Spanish locals, so a single-language site was leaving people behind before a conversation even started.
And the owner had no time to fix any of it. He works the service bay himself, so the answer could not be "learn to run a website." It had to capture leads around the clock, in more than one language, and stay up to date without a developer on call.
What we built
One connected system, not a stack of disconnected tools, all running from a single source of truth the owners control themselves.
Trilingual website (ES / RO / EN)
A premium, fully responsive theme served in three languages, each with distinct URLs and correct hreflang so search engines index the right language for the right visitor. Spanish for the local market, Romanian for a large local customer base, English for everyone else.
"Carmen" AI assistant, voice and text
One shared brain answering by voice or text: multilingual, financing-aware, and able to recognise the owners by name. She captures leads and fires an instant email plus a Telegram alert the moment someone is interested, so no enquiry is ever missed. Built on Vapi with Anthropic and OpenAI language models.
Self-service inventory manager
The owners log in and add, edit, or mark a car as sold themselves, with drag-and-drop photos that are auto-compressed on upload. The website and the AI assistant both update within seconds, with no developer in the loop.
Server-rendered per-car pages
Every vehicle gets its own server-rendered landing page with Vehicle structured data and a social-preview image, so each car is indexable, shareable, and looks right when a link is posted anywhere.
Inventory syndication feeds
Coches.net XML, a Meta catalog feed, and a generic CSV export mean the whole stock can auto-publish to car marketplaces and social catalogs from the single source of truth the owners already maintain.
Local SEO / AEO engine
A seven-article content cluster across all three languages with FAQ schema, LocalBusiness and AutoDealer structured data (areas served plus languages), an llms.txt file and IndexNow for fast indexing by both search engines and AI answer engines, and a dedicated contact page backed by a real backend.
One assistant, three languages, zero missed leads
Carmen answers by voice or by text from the same shared brain, in Spanish, Romanian, or English, whichever the visitor uses. She knows the financing options, recognises the owners by name, and the moment a buyer shows interest she captures the lead and sends an instant email plus a Telegram alert. A midnight enquiry becomes a saved contact instead of a closed tab, and the owner sees it the second it lands.
Fast and accessible by default
Speed and stability are ranking factors and most buyers browse on phones, so the platform was built to load fast, hold its layout, and pass accessibility contrast from day one.
The stack
The outcome
The platform is launched and live. The client runs their own inventory, the AI assistant handles enquiries 24/7 in three languages, and every stock change flows automatically to the website, the AI, and the marketplace feeds.
What was shipped is a full technical and AI-search foundation for a business that started with almost no online presence: findable, multilingual, self-serve, and built to be cited by both search and AI answer engines. This is a capability showcase, with commercial results to follow as it matures.
