Hi Dave.
Completely agree with everything Paul said, but prefer the original interior. Mine's an XF-S Portfolio (3.0d), 2011. Goes and handles brilliantly; a car that big shouldn't do what it can do! It runs rings around my wife's Audi TT! Only things that caused my bank balance to shudder are:
Tyres, tyres and more tyres (Heavy right foot!)
Rear wishbones
Inlet manifold
Recently had it ceramic coated, transformed the look. almost keeps itself clean, like a good cat should 😉
Currently working myself up to the issue of replacing the timing belt, but due to the lockdown, not such an immediate problem (currently on about 81000 miles).
There are lots of horror stories about DPF problems, but (crossing fingers here!), I have yet to be bitten by that, apart from once in the early days of owning it, but a good blast up the M23 and around the M25 resolved it in no time. Currently mainly doing shopping trips, but all is still cool!
Whatever you go for, make sure that absolutely everything works as it should, and post a pic!
Cheers,
Jon
