search_cars
ChatGPTSearch for cars on coches.net. The backend has its own NLP and parses all filters (brand, model, fuel type, price, year, mileage, color, location, etc.) from natural language — do NOT extract keywords or build a structured query. Use listingSection to filter by listing type: 'segunda_mano' for used cars (coches de ocasión/segunda mano), 'nuevo' for new cars (coches nuevos), 'km0' for zero-km cars, 'renting' for car rentals.
