Chance of a XC90. Looking for advice.

[walshy]

As thread title says after deciding to sell a couple of my cars I've now had a spanner thrown in the works in the shape of an xc90 at very handy money.
It's on a 07, auto with 132k on the clock and has almost a full service history.
What I'm looking for is hopefully some advice on any issues they have and what to look out for.
It's the Euro 4 engine I've been told so I think that rules out swirl flap issues I believe.
Also curious to see how much the road tax is as the gov website says over £500 but the equivalent car on autotrader is around £300.
Don't know a great deal about these but it's a car I've always had a soft spot for but also always had the fear of running one the same as when I had my Range Rover.
Any advice would be greatly appreciated.
Thanks

Just realised that I've put this in the wrong section. Feel free to move to general if need be.
