In the course of the rising fuel prices there are now various internet portals that mediate private car rental. So I put my car in there, there is a customer who wants to rent my car. He transfers the rent to the transfer and then after deduction of the commission to me. The car is then covered by a separate insurance. Actually a very good idea to compensate the rising fuel costs. Has someone tested this before? P.S. : I It starts from 15 euros per day for a smart convertible. In addition, insurance (full cascade + liability 8.90 €+ transfer fee1.50 €)+ petrol. So much cheaper than Sixt about 80 € per day.
