Advice for all you car people!

I started learning on my own, back in the '50's, when all vehicles had basically the same repair procedures. Bought the GOOD Chilton, Motor, and Mitchel manuals. I have several book cases, of these manuals, dating back into the '50's, going up to the late '90's. As the cars changed/improved, talked with other mechanics about fixes. Later on went to Part time tech schools like AC Delco at the GM training centers, and seminars put on by parts manufactures, and part stores. At that time these were all FREE (now you pay good money for training). Could not believe how few people took advantage of this free training. I went to everyone I could. At one time I was a ASE master auto tech, and had some truck certs. Now retired.
