Hi all, my dad has just come back from a holiday where he borrowed a rental car. He checked it on pick up and noted no damage. On the drop off he parked the car and left, 10 mins later an employee told him that their will be $400 repair fee for damage to the driver side door as seen here https://imgur.com/90kTbjZ
My dad is certain that it wasn't there when he left after dropping it off but unfortunately didn't take any pictures as he has always had good experiences with rental companies.
Just after thoughts on what you think it could be, we're thinking it could be cleaning equipment that they use got knocked against the car.
Update: Received a $450 fee, which is a lot better than we thought it could be, lesson here is to take pictures of the whole car.
How could you not notice that?!
