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!

Great Expectations Met
In these modern days of divisiveness, it’s hard to believe that a dealership with such poor loyalties would go above and beyond for a person that most would consider being the enemy. Dennis Freeman and Mike Santos made my family's 11 purchase a no-brainer. I was getting ready to take my 4-hour drive round trip to pick up a new truck for a family member. Until Mike called me and offered to deliver the truck on his day off. This type of customer service that keeps me doing business with a dealership full of Red Sox fans. They might give me a hard time for my amazing Yankees hat but it’s ok because this is what family does. I do not feel like a customer when I call or go into First Chrysler Dodge Jeep Ram, I feel like family. Thank you for making my family part of The First family.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Anchor Subaru has been servicing and selling us cars for
Anchor Subaru has been servicing and selling us cars for 30+ years. All we have ever driven is Subarus. We are very satisfied with all elements of Anchor Subaru. Amazing staff with Jack, Mike Plante and Brian Benoit. Our children now own Subarus from Anchor. I service my car nowhere else, as does my family. We have bought over 9 vehicles through the years, and will keep buying from Anchor. It is like being part of a family. They always have our backs.
