we recently travelled in Europe. Whilst we were there my brother, and sister in law, hired a car to travel in Spain and Portugal. They picked us up in Madrid and we travelled for 14 days then dropped it off in Barcelona. My sister in law took photos when they picked up the car, and highlighted existing damage with the rental place, and I took a video when we dropped it off. About a month later my brother got a message from them saying the car had some damage when returned. When my brother told them we had before, and after, photographs then, apparently, the problem was the info on existing damage hadn’t made it to the computer.
Just a warning to people, particularly if you rent in Spain, to make sure you have good before and after pictures; particularly for bumper bars and obvious scrape points. If you see pre existing damage make sure it is highlighted with the rental company. Make sure the video/pictures are offloaded in case something happens to your phone/camera. Don’t delete the images when you get back, you never know.
In addition, if possible record yourself asking google or siri what the current date and time is as well(showing the screen), and record their answer before starting to record the cars condition
