Please confirm the accuracy of the included equipment by calling the dealer prior to purchase.** Additional Information The area around Drive N-Motion Group carries a distinctly north metro character, where suburban neighborhoods, major roadways, and recognizable destinations all sit close together. Thornton's location in Adams County makes it a practical midpoint for people coming from places like Westminster, Commerce City, Brighton, and Denver, especially with I-25 and the surrounding arterial roads doing so much of the connecting work. But the setting is not just about convenience. There is also a strong local lifestyle component, with trips to Butterfly Pavilion in Westminster, shopping and dining at The Orchard Town Center, and easy access to community spaces across Thornton. On the larger entertainment side, downtown Denver's LoDo district, Union Station, and the stadium scene remain very much within the area's orbit. Drive N-Motion Group benefits from that balance. It is rooted in a familiar part of Thornton while still feeling connected to many of the places that define how people spend time across the northern Front Range.

AutosXchange Intel uses current dealer-advertised asking prices, not completed sales or appraisals. It compares the same trim and condition (new or used) where at least three are listed nationwide, and adjusts the expected price for mileage; it is not adjusted for options, condition or accident history. Similar listings are searched within 50, 100 and 250 miles of the dealer first, then the dealer's state, then nationwide. The left gauge spans ±25% of the expected price.
