Reservations

If the vehicle cannot be picked up by others, can the reservation be switched to another person? If I cannot pick up my reserved vehicle personally, can someone else do it for me? What documents do I need to have to pick up the selected vehicle? What do I do if I lose the credit card that was used to make my reservation? Do I have to have a user account to make a reservation? If I am late to pick up the vehicle at the specified time, how long will it be available to me? Can the reservation be changed before the vehicle pick up? What are the types of insurance available? The reservation process is completed but my voucher was not issued!
