I know the older cars, the ones where you can actually SEE the engine and what else is there. These newer ones with computers & sensors, forget it.
Me, too, Rudy! I can do all the basics, but,... Even some of my older friends feel left out now, you need so much equipment just to 'diagnose' a problem, & a degree from MIT!
I can change a tire, the oil, windshield wipers and possibly a headlight....That's it
