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.
Nicest, best performing truck I've ever owned

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.

Ive been in the car business for almost 18 years now and
Ive been in the car business for almost 18 years now and today I had one of the easiest, seamless, and outright outstanding experiences with my sales consultant Nick Cardillo, and General Manager Miles Bedford. I came from out of state to make the deal, and Im a bit particular with how I like my vehicle delivered so I gave Nick a task list before I got there to make it quicker and easier on him at the end of the month and he hit it out of the park. I was in and out in less than 1 hour with my new Hummer EV. He even made a special trip on his day off to make everything was perfect for me. Customer focused service is so rare nowadays and I am so thankful for the Tasca teams commitment to that. Bravo and much success in the future! I appreciate you all.

My experience at Imperial chrysler dodge jeep ram was very good. I worked with Ahmad Al-Jallad and Khalil Mansour and both were very attentive and explained everything clearly. They answered all my questions and gave me the best deal possible. If you are looking for a new or used car, I would recommend Imperial dealerships for your next purchase.

I recently purchased a Bronco, and the experience was nothing short of outstanding, thanks to Robert Sylvia. From the moment I walked into the dealership, they went above and beyond to ensure I felt comfortable and confident in my decision. Their deep knowledge of the Bronco's features, options, and capabilities was impressive, and they took the time to answer all my questions without any pressure. Robert and Team truly listened to what I wanted and worked tirelessly to find the perfect match for my needs. Their professionalism, patience, and genuine enthusiasm made the entire process enjoyable and stress-free. Even after the sale, Robert and his team followed up to ensure everything was perfect and that I was thrilled with my new ride ? and I absolutely am! If you're looking for someone who genuinely cares about their customers and takes pride in delivering exceptional service, I highly recommend Robert. Thank you for making my Bronco-buying experience unforgettable!
