My experience was fantastic.
My experience was fantastic. I've gone to Kris Dumont for my last 3 cars now, and I continue to go back to Banks because he is there. Buying a new car was fast and convenient for my schedule, and Kris goes above and beyond to ensure a smooth experience.

Great service, great business practice.
We purchased a Mazda CX-50 from Tulley Mazda in Nashua NH. We had a problem with the new vehicle and had to bring it to the dealer several times until the tech finally found the problem in a wire harness under the dashboard. We were given a loner each time we had to leave the car . Alex and their team are the best. They are professional in the way they do business. Have purchased cars from other dealers and never had such great service .
