I replaced my 07 S-Type 2.7D SE with a 14 Reg XF 3.0D Premium Luxury a couple of months ago. Once I came out of mourning (S-Type written off by next-door neighbour up the hill forgetting to apply his handbrake...) the XF is a revelation in every way. Haven't tried a 2.2D so can't comment. Only advice - think about trim level and what wheel size you get with it. Luxury has 17 inch wheels and 50 section tyres - but a rather ropey stereo. Premium Luxury has 18 inch wheels with 45 section tyres. Portfolio, with lots more electric gizmos to go wrong later, has 19 inch wheels and 40 section tyres - not so good on bad roads and easier to kerb the alloys. I think the 275bhp S has 20 inch wheels and 35 section tyres - ridiculous in my view unless you're up for track days. (Yes, I bought a Premium Luxury - Sportbrake - even better.) Also, not sure which models if any have a spare wheel rather than the useless can of gunk which ruins a tyre even if it works - maybe a factory option?
