South Dakota dealer fees: what's capped, what's real, what you can refuse
The short answer
South Dakota has no cap we could confirm on the dealer documentation fee. 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.

The fees South Dakota itself charges
These are the state's own charges on a new-car purchase. They're real and not negotiable, but the dealer should pass them through at cost: motor vehicle excise tax (4%), title transfer ($10 + $2 state technology fee), registration (Varies).
The doc fee, extended warranties, service contracts and GAP all raise the 4% excise tax, because they are counted in the purchase price.

| Title transfer | $10 + $2 state technology fee | — |
| Registration | Varies | Based on vehicle age and weight |
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 South Dakota
Verify with South Dakota: Ask the SD Attorney General's Consumer Protection division or the SD Dept of Revenue (Motor Vehicles) whether any rule limits or requires disclosure of dealer doc fees.
