My 99 GSR just went over 80,000 miles.
Other than oil changes, I haven't really done anything else in terms of routine maintenance since about 60,000.
What else should I have checked/done? And do I need to go to a dealership for this?
I've had my sparkplugs since 40,000 so I'm guessing I'll need to replace those.
Everything else seems to be fine.

I used to know all these things by heart, but haven't had time to keep up with my car hobby.
