I didn't do my for my C3, i changed the oil, tranny fluid, adjusted headlights, checked tire preasure, checked battery fluid levels, adjusted valve timing, brake lines, cables and such. Runs great, haven't had a problem yet i just change the oil every 500 miles and she purs like a kitten. Oh and here in Oregon they charger 200 Dollars to have the first service done?? whats the deal??
