In fact, it is never too late to learn auto repair, especially now that there are more and more private cars and more people who can drive, but fewer and fewer people can repair cars. It's because the auto repair is hard, and now it's all indoor repair, so it's not so hard. If you learn auto repair at this time and open a small repair shop yourself, even an ordinary oil change center, you will gain something. If you learn to repair the internal combustion engine, it will be even worse.
