?????????? 5/5 ? Outstanding Experience from Start to
?????????? 5/5 ? Outstanding Experience from Start to Finish! I recently purchased a Hummer from GMC and had the absolute best experience I've ever had at a car dealership. Jacob M. was incredible to work with?professional, friendly, and genuinely dedicated to making the process smooth and enjoyable. From the moment I arrived, Jacob made me feel welcome and informed. He answered all of my questions, took the time to explain everything about the vehicle, and never once made me feel pressured. His knowledge and honesty were a breath of fresh air. I also want to give a huge shout-out to the entire team?from sales to financing. Everyone I worked with was courteous, efficient, and made me feel like a valued customer. They helped me pick out the perfect vehicle and made the financing process simple and transparent. If you?re looking for a top-notch dealership experience, I highly recommend stopping by and asking for Jacob M. and his team. They made this Hummer purchase one to remember!

Great service, great business practice.
We purchased a Mazda CX-50 from Tulley Mazda in Nashua NH. We had a problem with the new vehicle and had to bring it to the dealer several times until the tech finally found the problem in a wire harness under the dashboard. We were given a loner each time we had to leave the car . Alex and their team are the best. They are professional in the way they do business. Have purchased cars from other dealers and never had such great service .

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.

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!
