If you call Berry Motor Group they know the common issues.
They had a XC70 3.2 they ran as staff car to around 320,000klm then my mate bought it and does big miles every week so must be well near 500,000 by now.
Well worth calling them.
You can buy VIDA and Dice on eBay. Or get the UK chap @Jamest5r_ knows to send complete setup laptop with no hassles.
The car will have issues now it's old so worth having VIDA to know what to fix easily without throwing parts at it which won't be cheap.
VIDA can tell you impending trouble too.
Buy parts from FCP Euro , lifetime replacement guarantee , yes, even send oil filters back oil too if you can, get new oil and filter free....Crazy good service. Parts cheap enough to counter shipping cost and Ozvolvo has discount shipping deal. See pinned post.
