Welcome chap! If I had done what you have before buying, I would have ended up with a much better car for my money! But then I’ve had immense fun putting mine right so no complaints!
As any will tell you, the most important aspect is a solid as rust free as possible body - there is a good reason why they are so rare!
Engines were cheap to fix but are getting pricier by the day especially as cast pistons are hard to find post covid impacts.
Look at some of the build threads and learn all about the common rust points / key issues to look for and ask questions. There’s no such thing as a dumb question, except the one not googled first
Also come to some events or meet Z owners local to you to take you out in their cars and to see the cars close up.
Hello - welcome.
although the knowledge available on here sometimes makes you think some drove from the womb.

Just too funny and true. I literally spat my tea out!
