My experience of an XC90, and something I will take forward to my next purchase is this.
These are heavy cars. I bought mine with 105k lies on. It now has 128k. Around 100k I would suggest that suspension parts, bushes, rods and links need replacing.
Bearing that in mind at circa 61k miles you are well away from such replacements. I would be ahoy to take a car with 61k miles on and in a few years begin to act proactively on it. Things such as Transmission fluid changes, Haldex Service, clean out the EGR pipework etc.
Routine run of the mill expendable items like brakes and discs are things you should do anyway, but a well kept vehicle goes beyond that, and the few things above are what I would do to keep your purchase in tip top condition.
