850/V70 Gasoline: Who has the most km with the 1st engine?

When I read the KM data here, I can’t get out of the astonishment anymore. I always thought that the 260,000 km of my 850 is already a very good result. But I often read something of over 300,000 km here. Is that actually normal with the 850? Even though I tell the acquaintances that my elk still has the 1st exhaust and even the shock absorbers are still the first, I only look in unbelieving faces. Also, I can’t find a rust, although the car is parked under a lantern from day one. I can’t imagine that I can get happy with another car again.
