Andre,
DeTomaso made standard Panteras, GTS Panteras, GT5 Panteras during over the years and differing models during the period you mentioned. It has been shown that VIN numbers were NOT always issued in sequence or order of construction. We can make "guestimates" on the number made of a certain model, but unless DeTomaso or someone else goes through the factory records, we will not have an accurate listing of type manufactured in any given year. Charlie McCall's comments above are on the money. I know of a 1989 GT5S ordered and made without the lower front spoiler typical of GT5S cars. It is more like a standard European Pantera front end.
