Why do we use 2H while 2F is mentioned on Wikipedia?

Little issue on these Toyota XS10 taxis, wiki mention released on December 19, 1995 but those are in production and wasn't complete until 1996. meaning all year 95 have set as 96 instead.

Japan origin for now, these were rebadged D-Max (which still develop in Japan for export only).

Another question would be the origin: DE or MX ? If MX, since which year?
Often we change the origin to the new country when there is a local restyling done, but that VW kept an overall look quite similar until the end.
So for this one I would use only DE as origin.

The jury is still out on whether these should be listed as 2004 though

You mean changing the few 2003 Última Edición to 2004? Not many indeed, for the four of them I'd do that manually anyway

They are not too many, should a mass update be done? (after your trip, of course)
