I will not give you a list of the most popular car hire companies in South Africa because popularity and excellent service are not always synonymous. I will tell you what a good car hire agency should be able to do for you and then you can use that information to see whether any particular one meets those criteria.
A good rental agency will offer you a cover charge for periods that are longer than two days instead of the daily rates. The longer the period the lower the cover charge should become, that is when compared to the daily rate.
You might also want to know if the cars have any extra features that you are going to need. A good car rental company will have roof racks for luggage and maybe sports equipment or extra storage facilities. They should be available if you need them even if they might not be for free.
You should also find out about the terms and conditions of insurance in relation to extra drivers. Registering extra drivers means paying an extra fee, but since you are leasing the car for a long period extra drivers should be registered for free.
A good car hire agency should be able to arrange your other requirements as well. That is book your flights, tours, cruises and so on. Although this will mean you paying more money. They should be able to tell you clearly the terms and conditions regarding your lease.
Most agencies will either not point out the penalties and conditions of breach of your contract. You should be clear as to what these are and how they affect you. Even though I will not list the popular ones I will just mention them quickly The most commonly used agencies in the country are Avis, RAV, Hertz and Budget. If you want to access them and compare them all at once just look up any of these:
