I grew up with mechanics so they used me for my small hands as a helper. I know what you mean about the computerized crap and even more. Today I've got Joe's car in the shop for fixing his brake lights, turn signal lights, and maybe the turn signal switch.? My brother that's a mechanic said take it to the garage ? They called me to find out how to get into the trunk and the only reason I know how is I read the book ? that's how I found out where the battery is when Joe needed a battery charge from AAA. It's pretty bad when even mechanics have to learn how to read.??Made my Dad teach me the basics of car maintenance. My first car was an old mini and that was just like a Meccano set, I even managed to changed the petrol pump in that and do all the brakes etc. saved myself a lot of money on garage fees. Modern cars are more computerised so topping up the fluids and recharging a battery are about all I can do now.
