I just bought a red 2003 S2000 with 9800 miles on it. I love this forum, thank you everyone who gave me advice before I bought this car Is there anything service I should do at this point? I don't think the dealer did anything to this car while it was there.

 

You would service based on TIME, since the mileage is insignificant. You basically have 3 year old fluids in it. Change them all unless you know for a fact that they've been done.
I'm talking about engine oil, tranny fluid, rear diff fluid, brake and clutch fluid.
Go to the FAQs at the top of Under the Hood. There, you will find "How To's" on all sorts of maintenance items, including the ones I just listed. While you're there, look at the "Oil Journals" so you know what kinds of fluids to use.
I suggest you get an owner's manual if you didn't get one. It will answer many of the questions that may come along.

 

Congrats!

 

Nice, and low miles! Welcome to the family.

 

Citius,

Follow xviper's advice.

Also, I warn MY00 - MY03 owners about the S2000's appetite for oil. Make sure you watch your dipstick at every fill up.

 

Welcome aboard!! Congrats on your new car!
