Negotiating the price and insurance with the leasing company and signing the contract are just like renting other things, just a procedure.
The leasing company will help you manage the vehicle, such as installing a GPS, but it is best to look at the condition of the vehicle before and after use, although the leasing company will also look at it. The profits are basically listed, and I rent 3/7 from you. If there are not many cars, the most conservative thing is: you can't make money, but the depreciation fee will definitely be earned back!
In case of accident:
Because car rental generally has compulsory insurance and property insurance, unless otherwise stipulated in the lease contract, you are only liable for compensation to the leasing company within the difference between compulsory insurance and property insurance.
