Where can I pick up rental cars in Canada? You can pick up cars at various locations. How much deposit do I have to pay for a rental car? A deposit is usually required when accepting the vehicle. Usually, it is only possible to pay by credit card. If there is no damage, the amount will be transferred back to you immediately after the return of the vehicle. In the event of damage, the car hirer will keep the amount and not send it back to you. In case you booked an offer including fully comprehensive insurance without excess, the supplier will pay you back the retained deposit. In the case of a fully comprehensive insurance with self-payment, you are liable yourself for the amount of the deposit. We, therefore, recommend that you book full cover. Like that you can be sure to receive your money back.
