It's pretty crazy to a guy like me also, a newbie. I bought my first Z in April 2020 as a Covid car project, after loving them from afar all my life. It's a 1973 original owner car with original paperwork, title, etc. It's white with red interior, and I've restored most of it, except kept the pearl white he repainted it instead of Kilimanjaro White.
It had sat most of the last 20 years, mainly I think because he was not a mechanic, and the mechanics he used didn't know how to handle flat top carbs, I'd guess. I've swapped in SU carbs, upgraded to a performance coated header and exhaust, etc. Having fun with the restoration. Even found the original radio in a box of his stuff.
I want to keep it and enjoy it, but man this market....
