Best car buying experience ever.
Larry Marcus was our sales consultant and Kendra Milan was our Finance Manager on our visit . From the time my wife and I walked in Larry us made feel at ease. Working thru the sales process with Larry was very smooth. We never felt any pressure during the time we were with him. He was very knowledgeable about the Acadia we were looking to purchase. When we were first looking at the vehicle he answered all of our questions. When it was time to leave with our new Acadia he took time to review the features of the vehicle before we left. He helped us set up some of the technology features during that time. Kendra Milan made the financing part of the purchase very easy. She was was very helpful and knowledgable going over all the paperwork necessary to purchase a new vehicle. Like Larry there was no pressure at all while working with Kendra. We were very impressed that we could come in and leave with a new vehicle on the same day. My wife and I agreed that this was one of the best car purchasing experiences we have ever had. We arrived at 2:30pm and were driving away by 6:30pm with a new Acadia. I would highly recommend Albrecht Buick GMC and Larry Marcus looking to purchase a Buick or GMC.

?????????? 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 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!

I bought a hard-to-find truck remotely.
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!

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.
