Midway Automotive
They were excellent. They got me right to the car I was looking for and They did not attempt to add any illegitimate fees to increase the price. They got the car ready for me so I could pick it up the next day ready to go. The experience of getting a car from this place went as well as it could have gone. I highly recommend them. The person who helped me was Frank Santino and he was easy to work with.
This truck has a jerk when changing gears sometimes.

They are fantastic
I purchased a 2008 honda crv67,000 miles. I thought maybe I had no chance to get into this Honda because of bad credit. But they assured me if this is the car I want they would make it happen and sure enough it did. The next day I was in my car and very happy. They were understanding, caring, helpful. They made sure the car was in mint condition when they gave it to us. It is running beautiful. I am so glad I went there. I would buy another car there in a heartbeat. They were absolutely wonderful. Thank you car max for making are dreams come true.
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!

Whenever I need to service my Enclave, I always reach out to John G. at Tasca. He always gets me in quick and makes sure I am satisfied with everything prior to leaving. I appreciate him always checking to see if something is covered by my extended warranty and always lets me know other costs up front. Thanks for your help!

Second time using Martys and very happy!
Can't get better than Marty's! We purchased a new 2021 Acadia through Marty's this go-around and had the pleasure of doing business with Paul. Great sense of humor, but even better businessman. We showed him a great offer from a competing dealership up in NH, that every other local dealership around here told us was impossible to make. Paul disappeared for a few minutes came back and said I can match that! So happy with the car, and happy we got to continue our relationship with Martys.

Of all the Toyota dealerships I visited, Dave Souza at Imperial Toyota was able to find the exact car I was hoping for (he kept looking long after we spoke in-person) and reached out when he found it. He was helpful, not pushy at all. …and I really like my RAV-4 Prime… it is so smooth and zippy to drive… and the supersonic red is extra fun.
