Skoda Octavia with 140,000km justifiable?

Moin, I saw a Skoda Octavia Kombi 2.0 TDI with 150hp and was quite enthusiastic about the vehicle. BJ 2014, DSG, a lot of equipment (ACC, traffic sign, elek rear flap, seat heating rear…) The costs are to be 11.500€ with double tyres. I only wonder if the already 140,000 km are too much. I need the car to commute a total of 600km on the weekends; 90% motorway. (estimated 30,000km a year) Of course the car should also last 4-6 years. I noticed it today and nothing negative, but I want to see it again from a workshop to make sure it’s safe. Is the km of power for commuting already too high? Is the car reliable beyond the 200,000km? What else should I pay attention to? Thank you for your answers.
