Found this on an Irish forum. Judging from the mods and way the new owner describes it as having a GT Pack (all Irish Z's are GT) I'd guess it came from the UK. Seriously ugly wheels.
This might help jog someones memory.
"GT Pack, Nismo Cat back Exhaust, Eibach 30mm springs, Antera 343's F: 19X8.5 R:19X9.5 Wrapped in Pirelli 245/35 and 275/35 Tyres"
