You know, I don't think I've ever seen an X300 or X308 with lattice wheels.

What I've now done is gone through all the XJ40s listed on this site and checked whether they have the lattice wheels or black grille veins (and gold cat's head badge), it turns out that none of them do, so I've renamed them as XJ6s. All the square headlamped Jag XJ40s (the Sovereigns) are named XJ6 now. Given the rarity of XJ40 XJ12s (only a tiny percentage of the overall total of XJ40s produced were XJ12s, 1200 out of 200,000, correct me if I'm wrong), it makes it much more likely that they'd use an XJ6 in a film, especially when one gets wrecked. Some XJ40s listed are too difficult to see properly (should all of these be listed?), so I've left them as XJ.

Now I would like to know how the X300 XJ12 looks different from the X300 XJ6, I have a feeling some of them are erroneously named as XJ12s.
