Skidmark. Can I just add my experience to this for you.
If I was to buy another XC90 (and I would) I wouldn't be bothered by the high miles, so long as it had a raft of receipts and bills for REPLACEMENT ancillaries such as wishbones, engine mounts, bets, rollers tensioners, discs and pads, swirl flaps etc etc. If you buy a lower mileage one, without that work having been done..... guess what you'll be doing if you keep it long enough......
I would be far happier with a well maintained and money spent on car, than one with low miles and nothing in the document folder.
