I cannot recommend D&D enough. They are courteous, friendly and professional. I brought my car in recently for what I thought was a minor issue - not only were the staff at D&D extremely helpful in looking at it straight away, but when it turned out to be not such a minor issue (and in fact pretty serious, requiring virtually the whole engine to be replaced!) they immediately recommended I take it in to the dealer where the repairs would likely be covered under warranty. They wouldn't accept any money, despite spending almost an hour looking at the engine and giving me four quarts of oil to get me from their shop to the dealer (the car was not safe to drive more than a few miles!). One of the mechanics even offered to give me a ride to my next engagement, since the car wouldn't make it. I couldn't believe the level of honesty and kindness - rare in this day and age - D&D thoroughly deserve their excellent reputation and I recommend them to everyone in the Leesburg/Ashburn area.
