Including the car agreement, the allowed mileage, the scope of use, and what decorations can be made for the car. Did the owner drive the car or did the wedding company let the newlyweds find someone to drive it? How to define the responsibility for vehicle damage caused by collision and scraping shooting?
If the car is dirty, is the wedding company responsible for cleaning the interior or the owner responsible?
Anyway, the villain is the gentleman before the villain, and I have considered all the details myself to avoid accidents and disputes.
Enjoy your rent.
