Hey Matt good to see another sunnycoast Z deviat has hit the forum.
Classic 30+ YO Zeds regardless, are not new cars, they are always going to require some tinkering just by the nature of the vehicle.
Depending on what you are prepared to spend $$$ will also depend on the level of vehicle available, example; improved modifications made mechanically and of course rust, brakes and suspension.
As a daily driver here on the sunny coast don't forget 240z's normally will not have aircond as a daily driver ugh!

Personally I use my 2001 S15 200sx, the best affordable and reliable current daily driver you could ever get to own and use, almost unbreakable and a magnificent drive up to Malaney. Good luck
