You need to be at least 18 years old to rent a car in Spain. Drivers under 23 will be charged a young driver fee.
You’ll need a valid driver’s license and ID or passport for a SIXT rental in Marbella. If your license uses another alphabet like Cyrillic or Arabic, you will also need an international driving permit.
Don’t worry if your plans are uncertain. Book your SIXT rental with the Pay Later option and cancel your reservation free of charge.
