Plata Garage

Evicron built for Plata Garage, a premium used car dealer in Sabadell (Barcelona), a website with a fully integrated management back office: a single Next.js application where the public catalogue, online reservations, appointments and analytics all share one database — no syncing, no external tools.

The challenge

A used car dealership lives on moving stock fast and never dropping a lead. The challenge was to digitise the entire commercial operation — stock, appointments, valuations, reservations and enquiries — in one place: publishing a car, answering a valuation request or confirming a visit had to take seconds and land in the same system customers see on the website.

Rather than bending a generic CMS with plugins, we built a bespoke application with 10 data models designed around the business: vehicle, reservation, appointment, valuation, message, shipping, schedule…

The solution

The public website turns the catalogue into a lead-generation machine:

• Filterable catalogue by make, fuel, transmission, price, year and mileage, plus free-text search.
• Vehicle pages with photo gallery, full technical specs and detailed equipment lists.
• Online reservation with a deposit via Bizum or bank transfer: customers can secure a car without setting foot in the showroom.
• Online appointments with a custom anti-overlap calendar: available slots stay in sync with existing bookings, and every appointment records the reason for the visit.
• Trade-in valuation form for the customer’s own car and shipping quotes by postcode.
• Blog with a Markdown editor and a floating WhatsApp button.

The site also communicates the dealer’s commercial promises — 12-month warranty, 130-point inspection and financing up to 96 months — on every vehicle page and key landing page.

The back office, protected with JWT and middleware, brings 6 management areas into a single panel:

• Dashboard with live KPIs: stock, cars sold, pending appointments, valuations and messages.
• Full vehicle CRUD with image uploads to Vercel Blob.
• Status-driven appointments and reservations, valuations, and messages answered by email straight from the panel (Brevo).
• Shipping requests, blog, weekly schedules with exceptions and bank accounts for reservations.
• A built-in analytics panel powered by Umami: visits, most-viewed pages and cars cross-referenced with reservations, referrers, countries and devices.

SEO for search engines — and for AI

This is where the project stands out. We implemented 9 types of JSON-LD structured data — AutoDealer, LocalBusiness, Vehicle, Offer, Article, BreadcrumbList, FAQPage, WebSite with SearchAction, and GeoCoordinates — so Google understands every car as a product with a price, condition and location, not just another page. A dynamic sitemap completes the coverage for classic crawlers.

And because more and more people ask ChatGPT or Perplexity before they ask Google, we added llms.txt and llms-full.txt files following the llmstxt.org specification: a machine-readable index of the site that makes it easy for AI search engines to cite Plata Garage with accurate data.

All of it runs on cookieless analytics: Umami measures visits, referrers and devices in full GDPR compliance, with zero tracking cookies. The business sees which cars attract interest and where traffic comes from, without intrusive consent banners or handing data to third parties.

The result: a platform where the website customers browse and the tool the team works with are one and the same system, deployed on Vercel (Frankfurt region) on top of Neon Postgres.
