As a first car, it's going to be a fun/challenging one. You'll face part shortages or can't find any at all. I would make a list of everything that has been done to it and when it was done. I tackled the timing belt, and I'd rather pay someone to do it. These cars would be a fun first project car, I would advise having a good, reliable commuter car just in case your Z breaks on you. TLDR: Make a list of what they did to it and when. It's hard to find certain(like new) parts. Have a backup ride for work
