There is no freaking way I would purchase a used CF frame unless I knew who owned it and was intimately familiar with it. I can inspect an aluminum or steel frame and make sound judgements about the condition, this is not possible with a CF frame. And there is so much trash coming out the big box factory country that may be questionable when new.
Could a CF frame last 30 years, maybe, but I would not ride it.
