They only work on Volvos...but they are so good that you want to own a Volvo just so they can be your auto repair place. They are the most honest business I have ever encountered. When we first moved here my brake light came on my car and I needed someone to look at it quickly. I was so new I didn't even know anyone to ask about repair places so I called all the dealers and was told there was a minimum wait of two weeks...despite explaining the near emergency nature of my problem. No avail. So I started down the Yellow Pages..and got to the Bs and reached Bethesda Imports...Mike Cunningham (the owner) answered the phone...two week wait for an appointment...I explained the problem...only car, brake light etc...he said "Bring it in." He fixed it. He then made sure we didn't get ripped off when we had our cars inspected for the mandatory Maryland inspection (and the "certified " place did try) and has had our business ever since. We also ended up buying a used Volvo from him for a second car--he gets and sells refurbished cars that he gets from the auctions. You can even tell him what you are looking for and what colors ...and he'll buy it for you to try...no commitment. Wow.
