Well if you read what i said in the first line, it must have not been in the same shipment. Duh. Serial numbers and compliance plates have nothing to do with each other. The serial number is copied off the car and stamed on the compliance plate, when the car gets here. (compliacne paltes are manufactured in australia) It might have been 5 cars behind th other in the factory, but for whatever reason, it wasn't on the same boat. Maybe it was held back at the factory due to quality controll Maybe they only shipped cars over 8 months at a time. I dont know. This would explain why the aussie compliance plates are 8 months apart. no one is saying that the cars were built 8 months apart. If there was a ship that had to turn back form europe and dump the cars in Australia, to would make sense that there would be alot more 240Z's around with 74 compliance plates, but this 1 car is the only eveidence I have seen.
