Type your own numbers and see the same car priced as cash and as a loan, with the taxes and state fees for South Dakota. Nothing you type leaves this page.
To see a lease, pick a vehicle. A lease is priced on one car: what it is expected to be worth at the end (its residual) and the leasing company's money factor change by model and by month.
An estimate on the numbers you type, not an offer of credit or a quote from any dealership. Starting loan rates are Rateous's rates for each credit range and term; they are not an offer from any lender. The documentary fee starts at an example figure, the state's legal cap where it has one or $599 where it does not, not any dealership's fee; each dealership sets its own. Taxes and state fees are estimates for South Dakota; the dealership's paperwork and your motor vehicle agency have the final numbers. Nothing you type is sent, saved, or used to check your credit.
The 4% motor vehicle excise tax is in lieu of state (4.2%) and municipal sales tax; no local tax applies to vehicle purchases.
South Dakota generally taxes the price before manufacturer rebates.
Leases of 28 days or more: excise tax applies to each lease payment (DOR Motor Vehicle Leases & Rentals tax fact).
