Our Story
Summit Automotive Partners is a privately-held automotive management group headquartered in Denver, CO. We were founded based on a set of firm beliefs: Long-term relationships, the empowerment of employees & customers and the innovations and creativity that come from a positive work environment. It’s not business as usual – it’s business as it should be.

Our Dealership Network
All of our dealerships are built on small town values but have the advantage of a big town network to support them. This network enables each to offer superior selection and volume, distinctive leadership and a consistency of experience that our customers have come to expect from their neighborhood dealership. It’s the combined enthusiasm and confidence of our manufacturers and our current and prospective dealership partners that supports our continued growth.
