On many sites you can book a car without paying an advance. In this case, you will not be guaranteed that you will receive the desired car rental. You can only rely on the honest word of the manager. If the manager receives another order for your dates, but for a longer period, it will be more profitable for him to simply refuse your service. In this case, he risks nothing but your loyalty.
On the service MyRentAuto when paying an advance for booking a car, you enter into a contractual relationship with the service provider, which impose clear obligations on the quality and provision of the service. The supplier is obliged to follow all the terms of the contract and legislation. Therefore, an advance is a guarantee of receiving the service that you have booked.
