I'm quite simialr in age, and I have a Jag XF as the "family" car along with my Zed.
the Jag is a 3.0 Diesel and i'm pretty impressed with its acceleration (only marginally slower to 60 than the Zed)
it does waft along quite nicely, munching motorway miles easily, but it does shift some when it needs to (also has the benfit of a "flappy paddle" manual mode if you fancy taking over from the auto box)
