First impression: car market is hell!

Hello, I wanted to give a first impression as a used car interested after two weeks of searching (on the internet and on site) or write to myself from the soul. So far I did not have a single positive experience. Something was ALWAYS “bad”, sometimes they were frayed belts, then missing maintenance slips and dubious check booklets, then consistently very low mileage with otherwise visibly well used vehicles (I guess that almost all vehicles more or less heavily manipulated on the tacho) etc. Besides, one is almost never interested in serious advice from the sales side. As soon as one drills professionally, immediately the interest of the opponent sinks into the groundless and one stands silently on the square. At the same time, it would be particularly important on the used car market to convince the properly critical clientele of the faultlessness of the supply. This does not take place. All history only on demand and partly then only wi At the moment I am close to canceling the action and buying a cheap new car on advice. I just don’t want to get into trouble, when I realize that I have been set on the cross. Although I have some rudimentary knowledge and various checklists (e.g. ADAC), but as a technical layman it is hardly possible to distinguish correct gap measurements from abnormal ones (in hardly any car the exact ones are correct, have tested this now several times. Also not on new cars by the way! ) and also otherwise: All pedals look little used, all seats have not sat through, no matter whether the car is supposed to have 10,000 or 100,000 kilometers down. That reads so beautifully. But the layman is in the end hipless on the square and can make a fool of himself. That is the greatest danger: to resist the desire for a car and supposedly good offer and to remain as objective as possible. I would have already become almost weak 2 times and only noticed the following day, that some things were not scientifically justified by the seller. There had e.g. a car sports rims and he said that they were from the previous owner. Then, however, he suddenly talked at another place (something later) about that the previous owner was a pensioner. Hello! A pensioner with sports rims? And that was still harmless. Do I possibly dramatise too much or is my instinct a little too sharp? What do you have for experiences and can you experienced my w Awful mistrust confirm or understand? Am very curious! Peter
