Personally I replaced my 2013 2,2 XF Sportbrake with an MB GLC 220D as the aircon would have cost around £2000 to fix (£30 TX valve, rest for labour!). I would have preferred to go for the newer XF sportbrake but was put off by the Ingenium engines which have a woeful reputation. The I pace does appeal to me, particularly if you are not bothered by depreciation as they are now available for a fraction of the "new" price although I am still nervous about EV battery longevity and "range anxiety".
