Since you are interested in touring a large city I can only assume that you will need the car for a period of more than two days. For periods that are longer than two days car rental agencies are prepared to give you a cover charge for the whole period as opposed to the fixed and daily rates.

You need to have thought about the time frame that you will need the car and consider the period that you need it in. As opposed to renting a car over weekends and holidays renting it mid week is always cheaper. If it’s possible schedule your tour to be outside these so called peak periods. You would be surprised how much money you can save just by doing this.

The next thing to thing to think about is the kind of places that you intend to tour. Is your tour going to be a within the city tour or you want to go further out.This will help you in deciding the type and size of car that you want bearing in mind fuel costs and fuel consumption. Having said that you can check out any of the following for some good deals:cheap car rental south africa, cheap car rental south africa, car rental johannesburg south africa

There are some tour operators that you could possibly sign up with but the trouble with tour operators is that everything is done according to their timetable. If you want a tour that will be flexible and accommodating then car rental is the way to go. Do a little research and compare the different agencies and don’t forget an online booking will get you a discount and is cheaper than booking directly.
