I bought my car at Koons Silver Spring since they were willing to go find the one I wanted, but I live in Arlington. I went to them for my first oil change at maybe 800 mi and it blew their mind that I wanted my oil change that early. I would have just done it myself, but they offer the first one free when you buy from them, so I just did it there. I told them they didn't need to do a full service just to change the oil, but they said they had to do everything. It took over an hour. Make of that what you will.
