Hi Paul,
I'm 67.5, retired about 3y ago, on my second XF-S after years and years of company cars. Highlights were an Impreza turbo, Golf VR6 and, back in the day A Calibra Turbo. Always wanted an XF - first was an impulse buy, a bit too old and needed work, but love it. got my current one (2017 xf-s, loaded with toys, but sadly, no cooled seats). Right now, can't think of anything I'd like to replace it with - and, as you say, certainly not electric (yet!).
Let's see what the future brings!
