Apparently, Nismo GTR VINs start with BNR32-100XXX, and regular GTRs start with BNR32-000XXX, and yours starts with a 0.
Also, I found a Nismo GTR on SAU and the VIN started with a 1. Also, at the end of the model code, there should be a 'RA' which stands for 'Nismo Group A Limited Edition' but yours says LTZG.
