The Monroney paperwork is provided by the manufacturer as a legally binding assertion of the features the vehicle was sold with - there's a copy of that in the article.
I'm not 100% sure of the law, but I wouldn't expect that to make a difference. The manufacturer may not be legally required to include the document if the vehicle isn't new, but if they choose to include one, I expect that it would still be required to be accurate and would still be legally binding.
