Having seen a number of XF's in different internal colours I have to say that the ivory interior is well worth the extra cost. Ours is vapour grey with ivory and the colour of the interior definitely lifts the car to another level. A chap in our village has a vapour grey with a black inside and it doesn't look anything like as classy as the ivory. Oh and we had it treated by the dealer before it was picked up (thought we'd cover every avenue to seek to keep such a light colour clean) and an unexplained dirty black mark just wiped off - most impressive.
