Awesome I was very pleased. They called me and told me they had a pickup I might be interested in so I went over and it was very close to what I was looking for so they give me a good price and I bought it.

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 .
There are 6 matching cars close to your year range.
