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.

I bought a hard-to-find truck remotely. Joel Picchi made the sale easy, answering all my questions, and helping navigate the challenges of an out-of state purchase. It ended up being one of the smoothest purchases ever! Thanks to the team for getting this awesome vehicle delivered to my home in central Maine!

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!

SALES REVIEW - HIGHLY RECOMMEND: After several failed
SALES REVIEW - HIGHLY RECOMMEND: After several failed calls with other dealerships in the area to find what we were looking for; we landed at GMC of Attleboro with Danny Jamgochian taking our call and answering all of our questions in a timely and professional manner. Danny was beyond helpful as we were purchasing two company vehicles that needed to be delivered to Nantucket. He always followed up with pertinent information [often on his 'day off'] with a zero-pressure attitude. Almost the entire transaction was handled over the phone which made our experience seamless being we were traveling over 2hrs away. Once we arrived at the dealership, Danny was focused on our needs and considerate of our time constraints. He also introduced us to General Manager, Gil Silva who helped facilitate us getting exactly what we needed/wanted with ease and with a family-oriented feel for our sales transaction. While we waited for the Business Manager, Dennis Yu to prepare all the financial paperwork - we were offered lunch which was a lovely touch. Before we knew it, our paperwork was ready to sign with the financing secured at the rate promised. While most clients dread going into the Finance office; Dennis was prepared and offered us the coverages that we needed without any pressure of selecting anything. We would highly recommend GMC of Attleboro to friends/family or anyone else reading this review! Everyone we came in contact with were friendly and made us feel like we were the only customers in the dealership. The facility was also very impressive, modern, clean/organized and offered many amenities throughout the Service Dept. [customer waiting lounge, snacks, TV, Wi-Fi] *Note: The second vehicle we were purchasing had not arrived at the dealership on the day we visited but that didn't stop Danny & the rest of the team at GMC of Attleboro from making the process of delivering it to us easy! The paperwork was sent ahead of time, the drivers delivered the vehicle in pristine condition, and they were both very polite and excited for us. Thank you to Danny, Gil and the entire team at GMC of Attleboro for making our dual vehicle purchase one we will never forget! It was truly a pleasure to do business with this group of talented individuals and we will certainly be loyal clients after our experience. Keep up the good work!

Justin was absolutely phenomenal to work with.
Justin was absolutely phenomenal to work with. At no point did I ever feel pressured, rushed, or on edge during the purchase of my vehicle. Justin was very friendly and fun to work with, he made the whole process immensely better. Even though I already knew what car I wanted going in, he took the time to explain all the extra features I didn't know about. Overall a very pleasant experience.

Great service, great people
I had a fabulous experience purchasing my Sierra. There is NO pressure which is a breath of fresh air. They are extremely knowledgeable, kind, trustworthy, and you will feel very confident in buying from them. I go there for service too and everyone remembers who you are and they come up to you to say hello. If I could give them more stars I would. This dealer is exquisite.

I called Vendetti Motors when the tire monitor light came
I called Vendetti Motors when the tire monitor light came on and showed no reading for the right front tire. The tire was not flat. The service manager fit me in the next day. After testing it was determined that the sensor for that tire was not working. It could not be reset. After being advised of this I asked the service manager to replace it while I waited. Vendetti?s service department is dependable, efficient and courteous.
