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 Portsmouth, Exeter, and Stratham areas.
