I mean, most people don’t know how to fix a car these days other than boomers.

Oh yeah, famously.

Sure there are the few which made it their career

North of 750k, sure. We professionalized the job of car repair and people who specialized in the field continued to develop their skills in an increasingly complex field. We didn’t just lose the skill of automotive repair.

We also introduced a number of module components to the chassis and the electronics, effectively making body work, car electronics, and mechanical repairs into three separate fields. So the process of auto repair got more complicated. Boomers did not keep up with the trade. If anything, they got phased out.
