Good morning, yes, there are many threads to it… And the various providers are quite critically evaluated. When I was looking for another car, I offered my golf at the brand dealer, where I wanted to buy the “new” one, for payment. He checked the car thoroughly, and also told me the result in detail. With this information I could sell the car on fair conditions (I could correctly provide information) privately. Andersrum it would not be wrong. If you want to buy a newer car from approx. 5000 EUR, you can also go to the brand dealer and have the car checked through. A deal with the seller would also be possible: if everything is right with the car, it will be bought, if not, the seller will bear the costs (or the costs will be shared). Also about the history of the car there would be no misunderstandings, at least if the history of the car would be stated as “check-booked”. Is there good counterarguments, i.e. arguments, which justify such an approach as outcast money, and yet better to go to the usual evaluators of ADAC, Dekra and consorts, if you have no expert advisor in the backhand?
