Include the documentation (doc) fee and any dealer fees or add-ons your quote treats as taxable.
Enter title, registration, plate, tire, and similar charges. Leave out any weight fee entered separately.
Optional products your quote treats as untaxed. Verify each item on the paperwork.
Money received after the sale, such as a state rebate. Reduces the cost estimate only.

Estimates for education and planning only—not an offer, quote, tax determination, or approval. Actual payments, rates, residuals, taxes, and fees depend on the dealer, lender, contract, and applicable state and local rules. If you want help comparing these estimates with an actual proposal, request a free deal review.
