You'll need to leave a security deposit just in case there’s any new damage to the car, traffic fines, missing fuel, and so on. If you bring the car back in the same condition, with the same level of fuel, and no traffic or parking fines, the supplier will release the security deposit within 30 days after the car's return. If not, they’ll take any charges from the security deposit, and the remaining amount will be returned to you.
ℹ️ The supplier will require a credit card in the main driver’s name to hold the deposit. The exact amount for each car can be found in the Rental Conditions.
