has leather ever been standard on any year? or as it always been an option?

im not sure what year, but i do know that there were supra's MKIV that did come with standard leather.

my 86 had leather, my 85 had cloth and my 89 has leather. my friends 91 & 89 both have cloth. according to one of the other websites i visit, leather has been an option for all non-turbo models.
