SDCL 32-5B-4 defines the taxable price as the total consideration minus the seller's credit for a trade-in, for new cars, dealer used cars and private sales. Total consideration includes cash, rebates, extended warranties and administrative fees, but not title and registration fees or federal excise tax.
