Haynes Manuals

I’m looking for a haynes manual, been looking around there are a load on ebay for the GPZ but only go upto 99 (mine is 2000) however (not reading the back) the new on goes upto 2005 but looks exactly like the same book?

does anyone know or will the 99 be ok with mine as it is a 2000 model

I can’t remember if there were any major revisions to the GPZ but I don’t think there were in which case the 1999 manual will be fine. Best check the revisions first though.
