When selling to another dealer, which of the following must be disclosed?

Disclosing the previous use of a vehicle, such as if it has been used as a taxi or police vehicle, is crucial when selling to another dealer because it directly impacts the vehicle's value, reliability, and marketability. This information is vital for dealers to make informed purchasing decisions, as a vehicle's past usage can indicate wear and tear or potential legal implications that may affect future resale.

While factors like vehicle color, interior condition, mark-up, and maintenance history may be relevant, they do not carry the same weight regarding substantive disclosure obligations as the previous use. The history of a vehicle's use can significantly affect perceptions of quality and reliability, which is why it is a required disclosure under regulations governing the sale of vehicles between dealers.
