NATIONAL Car Rental has launched a new version of its website carhirebooker.com, claiming enhanced systems including multi-booker access, reservation history for individual drivers and improved control for fleet managers.

Businesses can now choose a combination of multi or single booker access, with one controller overseeing all rentals. Kim Brown, National's marketing director, said: 'The addition of this function makes the site much more flexible but does not compromise rental control.'
