What You'll Build

The system should manage a fleet of vehicles including cars, SUVs, and trucks, each with unique identifiers, make, model, and year.
Vehicles should have states (Available, Rented, Maintenance, Retired) and transition between states based on operations.
Customers should be able to search for available vehicles by type, location, and date range.
The system should allow customers to book vehicles for specific start and end dates, with automatic state transitions.
Rental pricing should be calculated based on vehicle type, rental duration, pickup/dropoff locations, and any applicable discounts.
