There are a few listed in the wrong mk. I'm cleaning what I can but the fact that Wikipedia do not use the same mk as us is a problem, not everyone seem to use the same convention.
So there are early sightings with Mk4 front, and then it gets the incorrect Mk5 front. As SM99 linked, same seems to have happened with 2001 Transit LF51LHG - see comments in the Silent Witness page he linked - mains on other pages are normal where front is seen.
I would guess that the last one is probably a mk4 or mk5, since it seems rather new. There seem to be many Transit in Turkey so probably a good bet anyway
I'm wondering if they did something that kept the MK3 going as that looks like late MK3 seats. But the rest isn't really familiar to me from UK market Transit cab chassis.
