Are 30k mile tune-ups really necessary? What should I be looking for/doing in terms of maintenance?
Absolutely 30k tune-ups are necessary. The reason you change the fluids is because they lubricate metal components. Over time these break down and you're essentially runnin water in you engine, tranny, etc. (not literally but it's about the best way I can think to put it). I'm also a maintenance nazi, but it will most definitely prolong the life of your car.
Check your owners manual to find all the routine maintenance
