Sister Companies , not the same company. They still operate independently of each other under the parent umbrella of
Enterprise. Think Buick and Chevrolet. One more premium than the other.
With that said. Only Alamo has been somewhat cheaper on my rentals, but I value National Executive status far more and will pay a small premium to stick with them. Saving $20-30 is no big deal when I can choose from the Executive Aisle, request a certain vehicle in the wash and even take out of Alamo selection if you ask nicely. Not to mention the free days and promo's. Simply can't compare.
