I learned how to jump start my car without jumper cables. Get it rolling then pop the clutch. Of course, that wouldn't work on an automatic. But I don't own an automatic, never have. I also used to change my own oil and filter. That was fun ... well, was mostly 'fun' saying I knew how and could and did do it. But there is no need to fuss with that now. Besides, I'm not allowed to do such things in my condo building garage. Beyond that, I let the car's computer tell me when something needs to be checked and/or done. Okay, well, when the low tire pressure light comes on, I can handle that one myself, too.
