I wasn't going to say to anything, because I'm a novice, but I've never seen an Iroquois listed for anything near $60k. They top out at $30k. This is looking at dozens of listings, old and new.
I did speak with the fellow who bought the Iroquois I looked at earlier (it was advertised for a little over $30k, and then a little under $30k a few months later), it had some problems with the
holding tank but other than that was fine (at least as far as he told me).
I don't know what happened with the Gemini 3000, that was asking $32k but I didn't see anything horribly wrong with it. Doesn't mean there wasn't, I'm no surveyor. It was a very early 80's model.
