I know the N1/Nismo headlights, they don't look like that (all rectangular inside, no round rings). Also, the N1/Nismo R32 GT-R's only came in 1990-1991 (not 1994), and they had no ABS. Looking at the engine bay photo, this car has ABS.
Anyway, just go by the Jap chassis number (find it on that blue plate in the engine bay), not the rego or the new Australian chassis number on the vin/compliance plates affixed to the car after compliance (it would just show whatever year the compliance workshop put on the paper). Good luck with the sale. Nice car by the way.
