All vehicle prices shown on this website are for informational purposes only and do not include applicable taxes, title
fees, or license fees, which will be due at the time of signing. The advertised price does include our document service fee

Illinois, $350.00 in Minnesota, $180.00 in Iowa, and $599.00 in Wisconsin. The eFiling fee displayed assumes the buyer
resides in the same state as the dealership location, and are as follows: Illinois residents - $35, Iowa residents - $15,
Minnesota residents - $60, Wisconsin residents - $38. If you are an out-of-state resident, your actual eFiling fee may
differ and will be confirmed by a Kunes associate prior to finalizing your purchase.
While Kunes Auto Group makes every effort to ensure that advertised prices are accurate, pricing errors may occur. All
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
eligibility. Some incentives require financing through the manufacturer’s captive lender or are available only to residents
of specific states or regions. Kunes Auto Group works to ensure that advertised incentives are current and accurate;
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.

Finance & Lease Payment Estimates:
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
term in months, and the annual mileage allowance. Lease payments do not include acquisition fees, disposition fees,
taxes, or other charges that may be due at signing or at lease end. Not all customers will qualify for lease programs.
Lessees must meet lender credit requirements. Complete lease disclosures, including total amount due at signing and
total lease obligation, will be provided prior to execution of any lease agreement in accordance with the federal
Consumer Leasing Act.

Vehicle Information & Availability

ensure accurate display of vehicle information, including equipment, accessories, colors, and specifications, data is
sourced from multiple providers and may not always reflect the exact configuration of a specific vehicle. Vehicle photos
may be representative examples of the model and may not depict the actual unit available for sale. Accessories and

Vehicles may be transferred between Kunes Auto Group locations at customer request. A transfer fee of $300 will be
added to the purchase transaction to cover transportation costs when a vehicle is moved from its listed location. To avoid
this fee, customers may take delivery of the vehicle at the dealership where it is currently listed for sale.

Any fuel economy figures shown are based on the model year EPA mileage ratings and are provided for comparison
purposes only. Your actual fuel economy will vary depending on how you drive and maintain your vehicle, driving
