Can you pick any vehicle from ultimate series for flat upgrade or is it variable? Do you reserve prestige class vehicle and take any vehicle in prestige aisle? Also I am aware that few airport have ultimate series, and even fewer have prestige. And correct me if I am mistaken, are ultimate series and prestige the same thing? Hertz makes it too confusing for no reason.
