Well stopped off at a dealer just outside Peterborough and a nice(ish) XF premium 3l V6 diesel will be delivered on Sunday.
Cheap. Brisk (surprisingly so, in fact) starts and stops nicely. Trim in good nick. All the buttons and bells I could find work. And it was comfortable.
Now I'm nervous that I missed something, but it's got a 6 month warranty and the only MOTs it failed were due to tyres (4 new ones, but a bit cheap) so overall I think I'm happy.
Well not really, but I'll live. And hopefully I can walk properly again.
