A lot has changed since I first sent away for GM of Canada documentation, back in 1989. The new Vintage Vehicle Services now includes the dealership that it was sold through as well as the number of cars of that model type. And to prevent fraud, the paperwork is stamped with a raised seal. 285 GS 455 coupes imported into Canada. What they could not answer was where my GSX stood in terms of others imported. It is a late car, 05B build, #602. Don't know if any or how many were imported after mine
