Yes, please. The problem with the I & II, is that the first generation of the Trooper was - bizarrely - called Trooper II in North America, and until 1989. Then it was just Trooper.

Now that I've put a "mark" on all these entries, the american-spec ones read "Isuzu Trooper II I" which is a bit confusing. That's why I'm asking for a "Series" mark for these Troopers.
