Hired from Green Motion twice at Warsaw airport. First time service was very slow but car was absolutely fine. Second time I had the car for one day and they charged me Euro760 for a scratch on the roof - see picture. I did look over the car as I always do when I picked the car up there is no way I could have seen this in the basement of a gloomy multi story car park. It's the sort of thing that you would take 5 minutes to polish out if it was your own car. It is possible that a pigeon landed on the car in the day that I had it but it is extremely unlikely. My guess is that they just pay for the cost of the car by charging a customer Euro700 for every panel and then sell the car as is. Won't ever be using them again.
