Do NRMA still do vehicle inspections? Might be worth it if it passes your initial test drive assessment.
I see Staggers already told you about the gaskets, etc, associated with higher mileage units - still worth checking on this one too.
It's low enough mileage to have a good transmission that hasn't been ruined by the 'sealed for life' nonsense.
Starting it - the starter should whirr quickly when the button's pushed and start the engine; if the starter sounds laboured, it may need a new starter motor.
Test driving it, it should shift from 2 to 3 smoothly and without crashing or thumping.
If you buy it, it's highly recommended you get a transmission fluid flush and change (and transmission adaption resets via VIDA - this is vital), a Haldex oil change and filter, rear diff oil change, and an angle gear oil change done ASAP by a shop who knows what they're doing; not doing the adaptions via VIDA is only doing half the job. The fluids aren't cheap, but they're a lot less than a TF80SC transmission valve body replacement, etc.
You many know this already, but: In order to lower projected fleet servicing costs, Volvo-owned-by-Ford's marketing droids came up with an idiotic concept of mechanical butchery known as 'sealed for life' when it came to transmission oil changes, etc. But as the TF80SC doesn't have any filter, the fluid inevitably turns to crap-filled sludge and prematurely bones the transmission. It's the same type of stupid that prematurely kills GM's Alloytec HFV6 engines by specifying a 15K km oil change interval instead of the necessary every 5K km or annually, whichever is sooner. But when they're maintained properly, they don't clag out. So a service history check is prudent.
