For those of you who have already had this done, what does the dealer do at 15,000 that is over and beyond what they do at 5,000 and 10,000 miles?

They wanted to change the engine and cabin air filters. I already had done so, and told the service writer. He said that was the only additional items permformed. I asked if the 20 point inspection covered by the $49 oil change and tire rotation covered the rest of the 15K service and he said yes. Color me happy
