Thats just it, do it yourself, tune-ups are easy, if you need internal engine work done, use a engine builder, if you get work done, head reconditioned, radiator recored, ask for a warranty, then atleast you've covered your arse.
What does a minor service cost? 100-150?
for the price of two services,
buy a good timing light with dwell/rpm etc, $100
compression gauge $150+
feeler gauges $25
shop manual $25
now you can tune your car yourself,
get more tools, and do more!
