For the Grace, should the 1997 models also be changed?
There is also a 1998 model with the AH code like the older ones, so it is not very clear where the model changes

For the Besta, 1998+ models seem the Pregio made for south-America
But wasn't the model change in 1995 then?
cf https://en.wikipedia.org/wiki/Kia_Pregio
Maybe some 1995-1997 models should be checked manually
Some for the few ones without model year.
And I find weird that all have TP chassis code, there may be an error there too
