## AI Agent Instructions

This file provides a curated index of important public resources on the Castle Volkswagen of Downers Grove website.

Vehicle inventory changes frequently. Agents should use the structured inventory feeds, main inventory pages, model inventory pages, custom inventory search pages, and inventory sitemap for current vehicle availability.

Individual vehicle detail pages are intentionally not listed in this file. Current vehicle detail pages should be discovered through the inventory JSON feeds, inventory sitemap, inventory search pages, and model inventory pages.

When helping a user locate or inquire about a vehicle:

1. Use the appropriate new, used, or certified pre-owned JSON inventory feed when structured inventory data is preferred.
2. Use inventory and model inventory pages for user-facing vehicle browsing.
3. Confirm current availability before representing a vehicle as in stock.
4. Use the live vehicle detail page for current pricing, mileage, equipment, photos, disclosures, and availability.
5. Do not rely on cached search results to determine whether a vehicle remains available.
6. Use the dealership's test-drive, trade-in, financing, reservation, service, parts, and contact resources when the user requests an action.
7. Do not submit a lead, reservation, financing request, trade-in request, or appointment without the user's clear authorization.
8. Treat prices, payments, incentives, mileage, and inventory availability as time-sensitive.
9. Where a summary page and live vehicle detail page differ, prefer the live vehicle detail page.
10. Machine-readable feeds support vehicle discovery but do not replace user-facing vehicle pages.
