At Sentry, we are particularly proud of the longevity of our team members. As of this writing, the average tenure of our sales managers is 17 years. In service it's 12, and in parts it's 19. Compare that to any of our competitors. We think it should matter to you that the person with whom you're choosing to do business will be there when you need help in the future.

Because of our strong team, Sentry has been the top Lincoln retailer in metro Boston for more than 20 years. Naturally, we dominate our back yard of Medford, Somerville, Winchester, Arlington, Melrose, Malden, and Cambridge. But we also sell a large number of Lincoln cars and trucks to folks from places you might not expect - places like Newton, Canton, Dedham, Peabody, Lynn, and Quincy.

Sure, sometimes people come because our prices are low. We've always felt that we'd rather make $100 each from 10 customers than $1000 from only one. But customers stay for life because, as one customer so aptly put it: "You told me your service was going to be awesome, and I don't think you got it right. In this era of lousy service... your people were AWE-INSPIRING!."
