You have met my kids...in a different setting. I don't recall there being a computer problem. My kids may be city kids, but they have a fair amount of car knowledge, for their age. They can use tools, as well.
Working on a car for hours at a time would not fly. We tried that, already, in 2015 or so. My son is good for maybe 1 hour. My daughter? Maybe half an hour. Both kids are regularly at shops. My son and I replaced the front brakes on my truck.
