XF 3.0D buying tips

[XJ_Driver]

Good evening,

I've just popped over from the XJ section. My son Tom has seen a 2009 XF 3.0 Dsl for sale near where he lives, 159,000 miles. It's a nice looking car, and we plan to view it later this week. But any particular things we should look out for?

Advice appreciated.

Many thanks.
