What is your opinion about used cars with high mileage?

Hello, I’ve always been looking for up to 125tkm. Maintenance, condition etc is clear, important, I also look at it. But now there are vehicles that have 180tkm, 200tkm and more down. Whether the mostly short distance/long distance has been driven, can rarely be understood 100%. A car, which I liked well, has 187tkm down. But checkbook maintained and clean, relatively young Bj. With less km I would have to look at an older one in the same budget. I guess I can also have a long time pleasure with cars with longer mileage without bigger problems, or if it is better to look at a slightly lower mileage. Know friends, who swear on as low mileage as possible, another even said, if the more has run, then all the better. Because cheaper and that will have many wear parts new. However, in the same breath he has an older BMW with high mileage and only problems. Probably he does not have on the War How do you see the topic? PS: It’s a gasoline tanker.
