Leasing withdrawal

Hello Together, what are your experiences regarding the leasing withdrawal of the vehicle? There is an expert opinion from DEKRA. What is usually contested? I was of the opinion that stone strokes in the bumper, fender or windshield, are normal after three years and are not criticized…? My 7 was or is very well maintained. That the summer tires had to be changed and a rim is damaged was clear to me, but really would not have thought that St especially the bumper has to be replaced completely and must not be painted. Windshield probably also. For me it was not visible. Will still have to talk to my dealer, just wanted to know what experiences you have. Do you return the vehicles without any problems or additional payments?
