Difficult to advise anyone else on choice of options, I think it's a very personal thing.  Recently bought my XF.  It was a laborious tasks, but I listed ALL options for ALL model variants, then deleted all of the common features - surprising how many there are, which left the model specific or optional options if you know what I mean.  from there I was able to define which were the 'necessities', which were the 'nice to have', and which options I just wasn't fussed about.  Helped me a great deal anyway.
 
	Hope that's of use.
