Most car rental companies in Makassar require a credit card for renting a car. This is because the credit card serves as a form of security deposit for any damages or unpaid fees. However, there may be some rental companies that accept alternative forms of payment such as debit cards or cash deposits.

To rent a car in Makassar, you will typically need the following documents:

• A valid driver's license from your country of residence
• A valid passport or ID card
• A credit card in the main driver's name
• Proof of insurance coverage

If your driver's license is in English or uses the Latin alphabet, you generally do not need an international driver's license (IDL) to rent a car in Makassar. However, if your license is in a non-Latin alphabet or non-English language, it is recommended to carry an IDL along with your original license.

Most car rental companies in Makassar require the minimum age for renting a car to be between 21 and 25 years old. However, some companies may offer rentals to drivers as young as 18, but they may charge additional fees or have restrictions on the types of vehicles available.

The typical rental period for a car in Makassar is 24 hours. However, some car rental companies may offer shorter rental periods, such as 12 hours, while others may provide weekly or monthly rental options.

If you return the rental car late in Makassar, you may be charged an additional fee for each hour or day that the car is overdue. The specific late return policy and fees vary depending on the car rental company, so it is important to check the terms and conditions of your rental agreement.
