At Dennis Dillon we are so confident in our "Guaranteed Best Pricing" we will beat any price by $500 based on the following guidelines: • Vehicles must be new and have the same MSRP. • Vehicles must be the same Year, Make, Model, and have the same equipment. • Customer must have a purchase agreement signed and dated by a sales manager from the competing dealer. • Customer information and incentive eligibility must be the same as used in the competing offer. • Deal must be finalized in the same calendar month as the date of the signed purchase agreement from the competing dealer. • Demonstrators, service loaners, commercial and government fleet vehicles, limited production vehicles, special model vehicles (determined at the Dealership's sole discretion), and vehicles with over 200 miles do not qualify for this policy. • Dennis Dillon must have the right to purchase the vehicle from the competing dealer. • This offer applies to the new vehicle price after applicable incentives, and does not include accessories, trade-allowance, or any other item affecting the final sale price. • This offer applies to the vehicle price only, and does not include accessories, protections, dealer doc fee, taxes, registration, or title fees. *Best pricing is offered at the Dealership's sole discretion and is subject to change at any time without prior notice. The Dealership reserves the right to refuse to offer best pricing at any time, to any customer, for any vehicle. Please contact the Dealership if you have questions about our best pricing policy.
