When I used to rent from Hertz, I was always able to add my wife as an additional driver for free and without paperwork, even though she is under 25. It was apparently an automatic benefit.

Does anyone know if Avis offers anything similar? I've spoken to two CSRs and all I have got is that all drivers must be over 25, which I know is not true (you can definitely add younger drivers for a surcharge).

thanks!
