You can protect yourself by checking the car thoroughly and recording everything before the renter takes the vehicle. Ideally, the host and renter should do this together and keep separate records. This way, if a dispute arises, there will be evidence to show who was in the right or wrong.Please do the following:- Check the car’s interior and exterior.- Start the car and note the mileage. Next, register and report any dashboard warnings such as "check engine light" or some strange behavior, interior noise, or rattles.- Send the information either in picture or text form over email to keep track of records.- When you return the vehicle, please go over the process again.
