prices are subject to change without notice. The price you pay will be determined at the time of sale and confirmed in
your written purchase agreement. Please contact your local Kunes dealership to verify current pricing before visiting.

Rebates, Incentives & Advertised Discounts:
Advertised rebates, incentives, and discounts are subject to change or expiration without notice and may be subject to
eligibility restrictions, including residency requirements, financing source requirements, and vehicle or trim level

however, we cannot guarantee their availability at the time of your purchase. Please contact a Kunes associate to confirm
which incentives apply to your specific vehicle and situation.

Any finance payment amounts shown on this website are estimates only, calculated based on a combination of the
amount financed, the annual percentage rate (APR), and the loan term. Actual payment amounts will depend on your
individually approved credit terms. Not all buyers will qualify for advertised rates or financing. All financing is subject
to credit approval by the lending institution. A complete breakdown of your financed amount, APR, number of
payments, and total payment obligation will be provided to you in writing prior to signing.
Any lease payment amounts shown are estimates calculated using the manufacturer’s offered residual value, the lease
