Idaho dealer fees: what's capped, what's real, what you can refuse
The short answer
Idaho sets no legal cap on the dealer documentation fee; dealers surveyed there charge about $399 on average. With no limit, the fee is part of the price you negotiate: compare it across dealers and negotiate the out-the-door total. Below: what the law does say, the state's own title and registration fees, and the add-ons you can refuse.

Is there a limit on the doc fee in Idaho?
Idaho sets no dollar limit on the dealer documentation fee. The Attorney General's consumer protection rules define and regulate the 'dealer documentation service fee' but set no dollar limit.
Dealers surveyed in Idaho charge about $399 on average (an industry survey, not a legal figure). With no cap, it's a price like any other: compare it across dealers and negotiate the total.
What the dealer has to tell you
An advertised price may exclude the doc fee only if the ad clearly states its amount and that it is dealer-imposed, near the price (e.g., "PRICE DOES NOT INCLUDE $___ DEALER DOC FEE"). Credit ads must say "DOES NOT INCLUDE TAXES, TITLE, LICENSE FEES OR $___ DEALER DOC FEE". The fee must be for services actually rendered in preparing and processing documents.
If the fee isn't shown the way the rule requires, that's leverage: point to the rule and ask for it to come off.
The fees Idaho itself charges
Advertised prices must include freight, delivery, dealer preparation and all other charges. Only taxes, license and title fees, and a separately disclosed doc fee may be left out.
Fees you can say no to
Beyond tax, title, registration and the doc fee, most other lines a dealer adds are optional: nitrogen in the tires, VIN etching, paint and fabric protection, "dealer prep", and market adjustments. Ask for them to come off in writing; if they're already on the car, that's a price question, not a fee.
Verify with Idaho
Verify with Idaho: Check with the Idaho State Tax Commission whether sales tax applies to the doc fee, and with Idaho DMV for title and registration amounts.
