That sort of stuff is what wrecks any genuine certificate, in that it puts doubt in the buyers mind for anything they see.

My SL/R Torana has no paperwork from new. I bought it from a farmer in Queenbeyan and it's only got one tag. I don't care, I have seen these cars from new and have owned dozens, so I can pick a fake pretty well, especially an original un-restored one. My SL/R is the real thing.

But..... I know when I sell it I'm going to have all sorts of doubters because nobody believes anybody anymore.

These fake (or old stock original) certificates just make things worse.
