About Us.

Our Core Values

It takes a team to reach the top. At Summit Automotive we have lofty goals: to be the best network of dealerships in the nation. To get there, it takes good people, committed to a set of core values. Each of us lives with Humility, Integrity, and Passion every day, passing it on to every person who interacts with us in person, or online.

Our reputation is simply how we embody our core values with our customers. Each positive interaction is another step towards reaching the peak. When you need a reminder, look at this core value guide to remember what we are as a Summit team, our goals as people and as a company, and the heights we aspire to reach. Together we can achieve great things.


Humility starts with selflessness, doing what is best for your team and your company, before yourself. We are respectful, truthful, and confident but never arrogant.

We seek and provide honest feedback and are open to learning from our mistakes and successes in equal measure.

Humility does not mean saying everything that’s on our minds, it means speaking with good intention and always acting with Integrity.


Integrity is meaning what we say and saying what we mean. We strive to do what’s right, even when no one is looking. We want to gain our customers' trust, and the only way to do that is with fair, honest actions all the time.

We don’t make commitments we can’t honor or promises we can’t keep. We want our customers to feel like time with us is more than a transaction, it’s a positive encounter. An experience that makes them feel served by people who are genuinely Passionate about providing the best experience possible.


Because no one wakes up in the morning and says, “I want to be mediocre today.” We make some big promises to our customers and our stakeholders, and we can’t deliver on those promises without passion in our work and our processes. We love what we do and approach our job every day with energy, excitement, determination, and drive to enhance the customer experience.
