I was told that an appointment was not necessary for an inspection/oil change. I brought my car in first thing and it was ready to go just a few hours later. I work uptown, so I didn't pick it up until closer to 5:30pm, when I left work. I asked for just the inspection and oil change (told them what type of oil I wanted) and added that I wouldn't mind if they topped off the washer fluid. I asked them to call me if there were any issues or other items that needed attention and explicitly stated I didn't authorize any other work until I was consulted. They did exactly what I asked, didn't try to up-sell me or overcharge me or tell me XYZ needed to be replaced when it didn't. I'd happily take my car back.
