lol I've been wondering the same thing lately given how many seem to be coming through auction!
I know you already know the answer, but:
45 V-Spec N1s, 12 of which were track-only, most of the rest were purchased for road use/modification by race teams anyway. Mines obviously had one, so did TRIAL at some point.
To the best of my knowledge, 18 V-Spec II N1s were built, 3 of which, ironically, reside in Australia.
