About Us

In 1986, seeking to provide extraordinary Mercedes service, while treating both customers and technicians as he felt they should be, David Pettengill started a shop of his own.

For 31 years now, The Foreign Service has been living out that vision. The passion we have for our work and our commitment to excellence has been a winning combination for both us and our customers. Working exclusively on Mercedes has enabled us to attain expertise and familiarity not otherwise possible.

Our team enjoys working together to bring you the service you expect and deserve. Although very demanding, we find working on the world’s finest automobiles most rewarding. We all love owning, servicing, repairing and restoring the Mercedes Benz.

Whether your Mercedes be young or old, fast or slow, weekend cruiser or daily driver, you and your Benz will be in good hands with us.

  • "I just wanted you all to know how truly refreshing it is to deal with an organization that knows how to put the "customer" back into "customer service". You've certainly convinced me, and as long as I am driving Benzes - you'll have my business."

  • "I was hesitant to ship my 250SL all the way from Seattle for a major restoration, but after several conversations and reference checks I decided to go for it. I never regretted it for a moment. In fact, it turned out to be one of the best service experiences I've had with any shop, on any car, anywhere ... bar none."
