Worked with both MATTS they came to what I wanted for a payment. It was all done without going to dealership and that saved a lot of time. They were very professional, helpful and courteous though the whole process. The finance dept was smooth and explained all the paperwork for a fast transaction. I leased three vehicles from the new owners and will go back for my fourth. THANKS FOR ALL YOUR GREAT HELP.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

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 .

I love everyone with whom I've dealt with at Banks,
I love everyone with whom I've dealt with at Banks, particularly my salesperson, Kevin. Even procuring an extended warranty from the manager was painless and non-threatening! They were a joy from whom to purchase. Kevin has stayed in contact , as promised, to keep me informed about important follow-ups. Most recently, I returned to Banks to have a more thorough detailing done on my 2022 Buick Encore Gx and have a second key fob made that had been owed me at the time of purchase. The whole team did a knock out job on my car, offered me a loaner car to ease the burden of wait time and kept me informed of timing. This Buick was what I was searching for exactly-year, price and trim and although Banks is an out of state trip for me, I would do it all again and would recommend Banks to family and friends.

Why shop elsewhere.
I went in for routine maintenance and a minor repair. Service department folks from the desk to the mechanic on the job were, as always, courteous and pleasant. While waiting for work to be done I wandered out to look at vehicles. Had a nice chat with Mr. Poulin and my trusty salesman Aristedes. We talked about a potential trade and once Aristedes and I found the truck I wanted, he immediately went to work for me. Deals are always made with the customer's interest in mind. Our last 3 vehicles, and most likely the next 3, will come from Poulin.
