## Overview
This is a Symfony used-car dealership application. Customers browse and filter available cars, save favorites, simulate financing, contact the dealership, and book or manage appointments; administrators manage inventory and customer-facing operations. The graph separates those domain workflows from persistence and identity. The README is empty, so capability coverage relies on the supplied tree and source index; several controllers and subsystems were not sampled, and their connections are omitted or marked unverified.
Main entry points: [`src/Controller/ReservaController.php`](https://github.com/llazzarotto/sistema_autos_pp1/blob/main/src/Controller/ReservaController.php) (Appointment booking), [`src/Repository/AutoRepository.php`](https://github.com/llazzarotto/sistema_autos_pp1/blob/main/src/Repository/AutoRepository.php) (Vehicle queries), [`src/Entity/Auto.php`](https://github.com/llazzarotto/sistema_autos_pp1/blob/main/src/Entity/Auto.php) (Vehicle records), [`src/Repository/CitaRepository.php`](https://github.com/llazzarotto/sistema_autos_pp1/blob/main/src/Repository/CitaRepository.php) (Appointment queries)
