Welcome to Sentry Auto Group

We Do It The "Right Way"

Let's face it - you can buy a car anywhere. Why is Sentry different? What does it mean to be "the right way to buy a car"?

"The right way to buy a car" is more than just an advertising tagline. It means that we won't run newspaper ads designed to trick you into coming in on a deal that's not real. When you do come in, it means we'll treat you like a valued guest. And by "the right way to buy a car," we aren't just referring to the actual buying. We mean it as a philosophy that extends to your service experience as well.

How do we do it "the right way?" We can't give away all our secrets, but we start by hiring nice people. (As someone once said, that's easier than training people to be nice). Then, we have a whole set of guidelines (the Sentry Standards) that we strive to follow.

Sentry Auto Group is your best source for new and used Mazda, Ford and Lincoln cars in Massachusetts. Customers from all over New England, including Greater Boston, Shrewsbury, and Worcester will find a large inventory of new and used Mazda, Ford and Lincoln models.

If you're looking to purchase a new or used vehicle, we always have great financing incentives. And if you'd rather lease, don't forget to check out our $0 Down Leases! That's right - NO money down!

Located in Medford, Dorchester and Shrewsbury, Sentry Auto Group is convenient to everyone in MA.

Sentry Auto Group comprises Sentry Ford LincolnSentry West Lincoln, Sentry Mazda and our used car store, Sentry AllBrands.
