Does a used car with 80-90tkm always buy an almost broken turbocharger?

Hello, I looked at a used car, whose turbo and injectors were replaced the other day. The seller took this as a captivating argument, because I would never know when it will catch me with a car with this mileage. Quickly you get rid of 3000€. Does it exaggerate? Of course, you never know how the car was driven before, whether the oil intervals were perfectly maintained etc. I spent about 1000€ before for a van (diesel) with 70-90tkm, from BJ 2012. So far came a n Mazda 5, Ford Grand-Cmax or Toyota Verso consider, possibly the Caddy, but you should not take VW…
