Pricing. Advertised prices are valid through the end of the current business day and may change daily. The advertised price is the same for every customer, online or in store, and is not conditioned on dealer financing or the purchase of any other product or service. Advertised prices include a $999 dealer processing fee (not required by law). The fee is itemized in the pricing stack and included in the final price shown. Prices exclude only government charges — sales tax, title, tags/registration, and state or local fees. Out-of-state purchasers may owe different taxes and fees based on their registration address; any taxes shown are estimates confirmed before delivery. Prices reflect only manufacturer incentives available to all buyers; conditional incentives (loyalty, military, first-responder, college, etc.) are excluded unless stated and subject to manufacturer eligibility. Dealer-installed accessories already on a vehicle are included in its price. Protection products and other add-ons are optional and never required to buy at the advertised price.
Availability. All vehicles are subject to prior sale. ‡Vehicles marked with this symbol are located at another Aschenbach Auto Group store and are not currently on our lot. Transfers are requested case by case; availability, timing, and arrangements are at dealer discretion and not guaranteed. Contact our sales team about a specific vehicle. In-transit arrival dates are estimates and may change for reasons beyond the manufacturer's and dealer's control.
Accuracy. We work to keep this site accurate, but errors occur. If a vehicle is listed with an incorrect price or equipment, we will correct it once aware and reserve the right to decline a sale at the incorrect price. Photos may show optional equipment; confirm equipment and specifications with us before purchase. Fuel economy figures are EPA estimates for comparison only; actual mileage varies. Horsepower and other specifications are from manufacturer data for the trim and engine shown. Site content is provided "as is" without warranty of any kind, express or implied.
