I think thats a good idea - should be part of law - but i have seen a lot of variation in practice - have to research the Monroney law that created the stickers - pretty sure they have to be displayed on new vehicles available for sale, but never heard they had to be given to buyer. I have always requested it - somewhere I still have the one from my 1971 Charger 500.
From Wikipedia - for what its worth, I have never removed a Monroney Sticker.
"The
Monroney sticker or
window sticker is a label required in the
United States to be displayed in all new
automobiles and includes the listing of certain official information about the car. The window sticker was named after
Almer Stillwell "Mike" Monroney, United States Senator from
Oklahoma. Monroney sponsored the
Automobile Information Disclosure Act of 1958, which mandated the disclosure of equipment and pricing information on new automobiles."
"The Monroney sticker is required to be affixed to the side
window or
windshield of every new car sold in the United States and can only be removed by the consumer (Chapter 28, Sections 1231-1233,
Title 15 of the United States Code). A fine of up to US$1,000 per vehicle for each offense is authorized if the sticker is missing, and other fees and penalties are authorized if the sticker is altered illegally (including imprisonment).
[4] The act does not apply to vehicles with a
gross vehicle weight rating (GVWR) of more than 8,500 lb (3,856 kg)."
