Some SIXT branches accept debit cards as payment. Be sure to contact the branch you wish to rent from to see what forms of payment they accept.
If your plans are up in the air, we offer the option to pay on arrival. When you choose this option you can cancel your reservation free of charge.
The minimum age to rent a car from SIXT in the US is 21. However, some car categories require the driver to be 25, and an underage driver fee is charged to renters under 25.
