I have 70K miles on my 2003 Honda Civic Ex. I just got new tires, but besides that, the only maintenance I've done is oil changes and air filter changes. It's a 5 speed, and the clutch has been notchy when cold since 30K miles. The brakes are fine, I check those when I rotate the tires. Everything else works fine, but are there some preventative things I should do, or should have done by now? I plan on keeping the car until these tires go bad, so about another 60K miles. I'm fairly handy, I have done all but a couple oil changes and I can do brakes and what-not, but I've never driven anything this reliable. I usually just stick to the "if it ain't broke, don't fix it" idea, but I feel like I should do something.
