I'm not all too familiar with them but I wouldn't recomend one for your situation, honestly. They are difficult to work on, although the styling of them is timeless IMO, they still look modern to this day.
Parts will most likely be expensive if you need to fix something, and prepare for 1 hour jobs dragging to 4+ hour jobs because of how tight the engine bay is and where some things are placed.
Also, a few of my Nissan enthusiasts (and many other locals) say that the motors in the 300zx (GQ series I think) were the worst engines nissan ever made...whatever that means
