Hiring a car from the Johannesburg international airport should not be a problem since there are a number of car rental companies at the airport, and understandably so because this airport is the busiest in Africa. One of the greatest advantages of car hire is the fact that you can plan your own itinerary for visiting the various tourist attraction sites. Although hiring a car can be done right from the airport, it is worth considering making your booking in advance so as to avoid any disappointments.
