Learn More About Your Somersworth Subaru Dealership Serving Dover, Rochester, Barrington and Berwick ME

Tri-City was started over 50 years ago by Rene Plante and was one of the original Subaru dealers in New England. Tri-City continues to be owned and operated by the Plante family, now in its third generation.  Our principles are simple - outstanding customer service at competitive prices with the goal of creating long term customer relationships.  The Tri-City area is comprised of Somersworth, Dover and Rochester but we have customers traveling from all directions to work with our Sales & Service Teams.  Our customer family extends from the Lakes Region to Southern Maine and south including the Dover, Rochester, Barrington and Berwick ME areas.  

Tri-City's integrity and reputation is second to none and is something that is becoming harder and harder to find in today's automotive world.  It is in our core values from day one that customer service is paramount.  Word of mouth is the best kind of old fashioned advertising and our reputation is something we have worked hard to earn, we invite you to explore what our customers are saying about us, here

Our business has grown substantially over the last 50 years.  We have expanded the building several times and now offer a large showroom, modern customer lounge, high capacity service department and a weather proof drive-in service area for drop off and pickup.  The employee body has grown with us and Tri-City now employs over 65 hardworking local men and women.

Community involvement is the responsibility of any successful local business and Tri-City has been heavily involved in the community since its inception.  Whether it is thru sponsoring local sports teams to supporting Rotaries Tri-City has always been involved.  Subaru of America recently awarded Tri-City Subaru the prestigious Love Promise Gold Award for outstanding Customer & Community Commitment.  See what else we've been up to, here.
