What is a key feature of the Enterprise app regarding customer reservations?

The key feature of the Enterprise app that stands out is its ability to book and modify rentals. This functionality is crucial for customers as it provides them with the flexibility to manage their reservations easily and efficiently. Users can select their desired vehicle, specify dates and times, and adjust their bookings as needed without needing to contact support or visit a physical location. This capability enhances the overall customer experience by simplifying the rental process and allowing for immediate access to changes, catering to the dynamic needs of travelers.

Other features listed, like viewing promotional offers, tracking vehicle mileage, or communicating with customer support, play supportive roles but do not encompass the primary, core function of directly managing rental bookings, which is central to the app’s purpose.
