I just noticed this chart in the Nissan Skyline 32 GT-R Owners Bible, it gives the chassis numbers of the cars produced each month in Japan. Something pretty useful when it comes to figuring out if a 1989 Nissan Skyline GT-R is over 25 years old in 2014. Once they are over 25 years old, they will be both EPA exempt, and NHTSA/DOT exempt. The R32 Nissan Skyline GT-R was first sold in August 1989.
August 1989 BNR32-000054
September 1989 BNR32-001089
October 1989 BNR32-002089
