There is a thread somewhere in this ancient forum. The only numbered Nismo that would mean something is the Nismo that has #0001 on the plate and that isn't in the states. Not sure why they numbered them because they weren't limited edition. Fact is, Nissan stopped numbering Nismos in '15. A rare 370 for me, I'd say has a manual gearbox, never driven or less than 10 miles, has a Persimmon interior, and either Monterey Blue or Yellow. If it's Pearl White, it's not rare
