It was a waste of money for me. I had done my oil change before the 15k so I didn't have them do that. I rotate my own tires, so I didn't have them do that. So the only thing they did was fill my washer fluid and change my cabin air filter for $120. Supposedly they inspected my brakes, "tightened" bolts under the car, and did some other inspections. In other words, they didn't do jack. I'd wait till the 30k one to do anything. The 15k one is worthless unless you are having problems with the car.
