We are going on a road trip through Namibia and Botswana. We are flying in to Jo'burg and now have a choice:
1) renting a car in Jo'burg and driving to Namibia - Botswana and then back to Jo'burg
or
2) flying to Windhoek en renting a car there and driving a loop trough Namibia and Botswana back to Windhoek and fly back to Jo'burg.
Aside from the additional distance one would have to cover to get from Jo'burg to Windhoek by car, are there any other considerations such as price of car rental, quality of car rentals, etc?
Which car companies are recommended for hiring a 4x2 car in Windhoek?
