I just rented two cars in the NY area and both times (LGA and EWR) they were out of Neverlost cars. Talked to the manager at EWR and he said they get booked pretty quickly and usually go out on Mondays with business travelers and then get returned later in the week so they have a lot of them on the weekends. I waited around for 15 mins and he kept radio-ing his employees and finally a Ford Excursion popped up with Neverlost and I took it. I hate traveling without it. But like the OP, I print out maps as well as a backup.
