2019 GMC Terrain Service
I delivered my Terrain to the service department and waited in the lounge. When the service was completed I paid with my GM credit card. The service department delivered my vehichle after it had been washed.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Very friendly and personable.
We were blown away at just how easy of a process it was to buy our car from this dealership. Everyone was absolutely fantastic. That includes Colleen, Matt, Kyle, Joe, Peter, and the rest. We would love to deal with them again. We are VERY pleased with the car, the service, and the general attitude of everyone there. I highly recommend them.

Car looked better than new after repairs
An amazing experience with the service department and collision center at this dealership after my car was damaged by a fallen tree. The process right from the beginning was flawless. Getting the car to the dealership, getting the rental car, the time it took to get the parts and do the repairs was quicker than expected. The ease and efficiency of the repairs and the quality and timeliness makes Gates GMC. Jamie Laskow and his team get 4 stars from me! I will definitely recommend your dealership in the future.

Great staff, nice looking cars all over the lot
Great staff, good prices, Greg (salesmen) was amazing, and Jim got me best rate possible even though he didnt have to he kept trying and got me a nice low rate. Now I hope and pray my 2014 Nissan Murano can last me as long as my Toyota highlander did (14 years) before it was totaled while parked. Will look to do business in future with Daddaro Dealer

I recently had an outstanding experience purchasing my 2024 GMC Sierra AT4 at Gates GMC in Windham, CT. From start to finish, the team at Gates exhibited clear communication and professionalism, making the process seamless and stress-free. What stood out the most was the transparency and honesty in every interaction, with no hidden agendas or surprises. I felt valued and understood, and they made sure all my questions were answered. I highly recommend Gates GMC for anyone looking for a reliable and customer-focused dealership. Thank you for an exceptional experience!

Great experience
We went to D'addario's about a used Volkswagen SUV. I worked with Ed and he was phenomenal! Never made us feel pressured and the dealership worked with us on getting into the car at the price we wanted. Would highly recommend.
