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.
I plan on going to Koons Falls Church for service going forward due to convenience. I've only had one experience with them so far, but it was pretty good. Koons Silver Spring didn't provide an inspection sticker since they are in Maryland and I live in VA, so I went to Koons Falls Church to have them do an inspection. I told them the car was brand new and asked if they could just slap a sticker on it, but they said they would have to actually inspect it. It's also first come, first served for inspections in VA, and I went at the end of the month (already got one ticket, so didn't want to wait), so I prepared for a long wait. Maybe 5-10 mins later they came over to me and said it was done and they weren't going to charge me.
Anyway, I'll prob do my next oil change myself, but will prob have them take a look over it and change oil after 10,000 mi/1 yr.
