I am hiring a car in South Africa when we travel in September. In Australia, I have never had a deposit charged to my card when hiring a car. They have pre-authorized the card but those funds haven't been taken out of the card. I was still able to use that money.
A few people I have chatted to have said that in South Africa they will take a deposit + a the total charge of the rental, and refund the deposit upon return of the vehicle.
I am hiring with Avis. Does anyone have any experience with what amount is charged with Avis, or any other large car rental company in South Africa?
