XC60 D3 5cylinders with high mileage purchasing advice

Hello, I love the purchase of a used Volvo XC60 D3 (2,4l 5 cylinders) AWD automatic with 163hp from 2011. Visually and equipment-wise, a model would be very good for me: among other things – are back camera, leather, panoramic roof, Navi, stand heating, Xenon with on board. Since the used car market currently does not give me much, I have already very stiffened on this candidate, but the mileage of 275 000km makes me a bit of a stomach ache. Is this mileage with the said topic? I read again and again about Kop sealing – or head cracking problems, is this engine also affected? Called up for the FZG. 10 000€ (in Ö) I still plan to drive in about 100tkm, there are already experiences with so high KM stands, especially in relation to engine/geartronics? A small manco is the front fender, here there are a few rust spots due to stone strokes in the wheel run.
