I still work on my own cars as much as possible. The computer has changed how you diagnose things but not the basic priniples. My 1998 truck has a 350 gas GM engine, the same one that came out in the 50s. A computer tells it what to do now so all of the doodads that needed tuning and maintenance are essentialy gone. No points, carburetor, or timing to adjust. Heck I still have a distributor but if I loosen the retainer and turn it, the computer readjusts the timing by itself. The typical work of changing brakes, oil, ignition parts, and other things on schedule is all that's left. The good news is that after 145000 miles this old school GM350 burns no oil.
It takes a village to raise a kid and if the village doesn't include any hands on DIY type people then our youth will suffer.
Next time, change your own oil. Teach a kid how. I've had to teach all of my brother inlaws these types of things. I've had great fun getting each one of them to get over the fear of electricity by touching both terminals of the car battery, they thought they would be killed!!
