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.
Our dealership network currently includes: Action Nissan in Nashville, Tennessee; Berlin City Auto Group with locations in Maine, New Hampshire and Vermont; Groove Auto Group in the Denver Metro area; and Groove Silverthorne in Silverthorne, Colorado. Together, they represent 19 great manufacturer brands.
It’s the combined enthusiasm and confidence of our manufacturers and our current and prospective dealership partners that supports our continued growth.Get More Information
