That figure is for the 1991 model year for the United States only, and does not include cars built for Canada or anywhere else in North America (e.g. Mexico).
We don't know production figures by model year for Canada, but we know NSX sales by calendar year: 156 in calendar 1990 and 253 in calendar 1991 (
ref).
And we know from the VIN that your car was built for the U.S. market. :wink:
Just lookin' out for our friends north of the border... :smile:
