they don't. Which is why i was surprised. They ran down the list of services and it included way more than just a checkup. They change almost all the fluids and do timing checks, new gaskets all over the place. I should have written it all down. It was quite the list. So i guess the question is... is all of that needed? I know the Si's don't need a lot of stuff changed over that the other models do at the same mileage. Spark plugs for example. I have the Helm Shop manual at home, i'll have to give it a good once over tonight. I'm so not in the mood to call 10 shops and get a cheap price only to end up with shitty service. Argh.
