Yes Last year Nissan said in reply to me about the UK we had
(V1) MY13 (inc Part of MY14) 370Z NISMO – 120 Brought into/Registered in the UK
(V2) MY15 & MY16 – 180+ Registered in UK – Still on sale so growing number
Not sure how many have been registered since April 2016 - I will ask for an update from Nissan
Our numbering was Europe - in the US they ran 4 digit and from 2009. In the US they also included the year on the numbering - which we didn't have - but in the UK it was always considered (although I never knew it) to be a limited run of cars. The V1 was as far as I know never sold in Australia as Nismo have only been over there for the past year or so. So all of them are likely V2 (without the numbering)
I will contact Nissan to see if they are able to provide any answer. Last time it took a while for them to get the info but they were very helpful. I will ask again.
