Which of the following is NOT a suggested method to improve DE%?

Increasing loaner vehicle inventory is not typically considered a method to improve the DE% (Days Energy percentage). DE% refers to the ratio of vehicles rented to vehicles available for rental, so strategies to improve this metric generally focus on enhancing customer engagement, effective pricing strategies, and maximizing rental transactions.

While having more loaner vehicles can facilitate rental opportunities, it does not directly influence the DE% as effectively as the other options. Pushing upgrades on rentals encourages customers to spend more, thereby enhancing revenue from each rental transaction. Setting walk-up rates aligns pricing more closely with customer demand, which can lead to increased rentals. Being aggressive on phones suggests proactive communication and customer service, likely resulting in more bookings. Therefore, options that focus on immediate rental transactions and customer interactions are more suited to directly impacting the DE%.
