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 32 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 have been a customer of The Foreign Service since the 1980s. I have always found them to offer services that are in the best interest of the customer; not trying to sell services just to make money. I recommend The Foreign Service without reservation. "

  • "I have used the Foreign Service for the past 10 years on my ML500. They try to strike a balance between items that need repair versus items that can wait. It will be VERY hard to buy another brand as they only specialize in Mercedes-Benz. I cannot recommend them enough!!"

  • "I recently had an issue the local MB dealer could not seem to fix, and just kept ringing up service bills. David and his team were able to diagnose the problem correcting work done by the local dealer... they really know their stuff. If you own a Mercedes in the Triangle, you should be their customer! "

  • "My decision to buy a Mercedes Benz was due in part to the great service my wife receives on hers. Great prices compared to dealerships. Sure, you don't get the dealer's foot massage and a latte, but you drive away knowing that your car has the best possible service that it can receive. "

  • "The Foreign Service has done a great job in taking care of two MBs for me. One for more than 15 years, has 176k miles and still runs like new. Recently got a 3rd MB and will be getting it serviced at TFS. Friendly staff. Reliable work at a fair price. "

  • "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 have never had a bad experience with Foreign Service, unlike with dealerships. They have maintained 4 cars for us over the years, and it's always been great work. I recommend them with no reservations. And having loaner cars available is an added bonus. "

  • "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."

  • "The job you did on my 280SL is incomparable. The car is in better than new condition and I am proud to drive it anywhere. It is really reinforcing in this day of "quick, slick and overcharged" to meet quality people like all of you, who actually do what you say when you say."
