I am definitely not a PRO but I will still rebuild one or two engines before my career is over. I love working on cars, its therapy and a stress reliever in the 21st century. I can drive somethin I built with my hands..

BTW Mechanics are no different than the spectrum of human nature, scientists, housewives and hotdog vendors,and we humans are not saints nor are we entirely evil.

In fact, most mechanics are very very decent and honorable, its the shop managers I dont trust and am wary of...

Anyway as a true amateur I would rather use vice grips on my brake lines than take my car to these shops..at least it meant I tried...
