Expected lifetime – your opinion?

Hello everybody, I’m interested in your opinion: My V50 (a D3 from 4/12) currently has a good 66,000 km on the clock and gathers diligently on. Until a few months ago, most of the kilometers came from the long journeys between Munich (my home) and Dortmund (my little daughter’s home). For some time now, many trips between Munich and Italy (my friend’s place of residence, easy distance about 420 km) are added. In other words, my V50 is up-to-date and until further notice It’s a lot on the highway. It’s actually almost all long-distance kilometers that the car collects, between 3500 and 4000 km per month. In the city itself I’m practically never driving a car, but public transport. I’m now thinking about the expected lifespan. My plan was actually (and still is) to drive the car to scrapping because I really love it. But I’m starting to wonder if a sale now, since the kilometers are not too many or would it make more sense to keep the V50? How long will it last, probably, if you can predict it on the basis of your own experience? I have read a lot in the forum here about expected repairs, weak points, etc. at the V50. But what I lack are long-distance experiences. If it is important: I have three years of connection guarantee, but the relativizes itself also mi t increasing mileage a bit. Greetings Thomas
