There is one thing you have to come to grips with—license, title, and registration fees are the same for all consumers, based on the ZIP code where they live. These are state fees, not dealer fees, and are merely collected by the dealership and sent to the state.
The document fee is also known as a doc fee or paperwork fee. It covers the cost of processing the paperwork relating to the sale of the vehicle, including the filings at the DMV, license plate, checking a trade-in value, sales contracts, and any other paperwork.
