Great dealership.
Great dealership. High quality used cars surpassed only by their high quality employees. Salesperson (Alex) and General Manager (Taylor) were great. Taylor is absolutely the best person to deal with. Honest, straightforward and he truly wants to get you a vehicle you love. He's not just trying to sell you a car. He is trying to make you love your purchase.

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!

I had a great experience at Central GMC of Norwood thanks to Jake. He went above and beyond to help me with my truck purchase and even took the extra time to help me empty out my trade-in. Jake was professional, friendly, and made the whole process smooth and stress-free. I highly recommend asking for Jake if you’re looking to buy a vehicle — he’ll take good care of you!

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.

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.

I had an excellent experience at McGovern GMC
I had an excellent experience at McGovern GMC Westborough. Ben, my salesman, was fantastic—he was helpful, never pushy, and kept great communication throughout the process. He really listened to what I wanted, respected my budget, and even took the time to get to know me while sharing a bit about himself, which made the experience feel personal and comfortable. Omar in finance was just as great—super friendly, honest, and transparent about everything. The dealership itself was clean, well-maintained, and in a very convenient location. Overall, the entire process was stress-free and enjoyable. I’d highly recommend them!

I had a great experience working with Nate Resendes.
I had a great experience working with Nate Resendes. He was incredibly attentive and knowledgeable, taking the time to answer all my questions without ever making me feel pressured to buy. I appreciated how understanding he was about my situation — I’m not quite ready to make a purchase yet, but wanted to get a clear idea of what to expect. He gave me helpful, honest information and made the whole experience comfortable and informative. When I am ready to buy, I’ll definitely be coming back to work with him specifically. Highly recommend!

Honest, courteous service with no pressure from the sales
Honest, courteous service with no pressure from the sales person. The price of the GMC Canyon Denali and the value of my trade was more than fair. It was so good I drove four hours to get there and I’m glad I did. Thanks to Doug Lee and the entire staff at McGovern GMC for a great Truck buying experience.
