DepositFree should not be sold as Full Coverage, but it can be a part of your Full Coverage service.
Full Coverage is often called a CDW, collision damage waiver, or "full insurance" provided by car rental.
As usual, Full Coverage service covers the most typical expenses in car rental: tires, glass, fuel, scratches, improper returns, and cleaning.
However, you cannot usually cover huge traffic fines and significant car damages with your full coverage. For this purpose, car rental company can either use a deposit, or DepositFree service.
You can sell DepositFree as a part of your Full Coverage service.
For the car rental company, it's a great chance to cover possible expenses that come on top immediately and without any hassle.
However, the client should be fully informed about his liability and the exception list for your Full Coverage cases.
We do not recommend using a "Full Insurance" term when it comes to Full Coverage service provided by your car rental agency, because it may cause confusion between your service and insurance as is. From the legal point of view, your car rental company does not usually provide insurance services as they are.
From the marketing point of view, your DepositFree Full Coverage is a profitable, safe and easy service for your clients and managers.
