BWAAAAHHAAAAHHAAA, which course would that be ???
It's still possible to do most work yourself--I do, on my cars. The only time I have to take them to the professionals is when a job requires a dealer scan tool. While I do my own engine rebuilds, etc., most people would never need to do any of this. Rather, a short course teaching them how to do brake jobs, battery, belt, and fluid changes, and a few other things would be enough to allow an individual to save on most repairs. Timing belts would be something else to consider, but more involved on most cars.
