Correct me if I'm wrong but aren't tune ups mainly: changing sparkplugs, rotor, distributor cap, checking all fluids and changing what's neccessary, a test drive to see if any problems are present and check wheel and brake wear? I use to have the dealer do their tune-ups and that's mainly what they tell me they do; costs about $150; any thing else is extra. Most of this stuff you can do on your own. I did the last tune up myself and only cost me $50 in parts.
