Which item must remain in the window of a new motor vehicle until it is sold to the ultimate purchaser?

The Moroney label must remain in the window of a new motor vehicle until it is sold to the ultimate purchaser. This label is a federal requirement that provides consumers with essential information about the vehicle. It includes details such as the manufacturer's suggested retail price (MSRP), standard equipment, optional equipment, and fuel economy estimates. The inclusion of this information is important for transparency and helps potential buyers make informed decisions about their purchase.

The Moroney label serves as a vital resource, ensuring that the buyer is fully aware of what they are purchasing and the associated costs. Other items, such as dealer advertisements, price stickers, or sales flyers, may not have the same regulatory requirement and can be removed or replaced during the sales process, as they do not provide the comprehensive information mandated by law.
