The brochure that I assume every dealer had for the Stinger - I got mine early, before the US cars arrived (but the Korean spec cars were in the showrooms) iirc. The two different dealers I have visited for test drives also offered one to me - which I declined as I had one already.
It's about 30 pages, very nicely printed, contains lots of great info about the car and its development. The comment about reduced top speed in on the color and wheel selection page, second-to-last (pages are not numbered).
It might come down to whether any legal standard or precedent exists for making vehicle specifications available to potential buyers. Between the brochure and the website, is it an either/or, or do they need to contain the same level of detail? Certainly for decades the brochure was the only document provided to shoppers, but that hasn't been the case for probably the last 20 years.
