When I was young and couldn’t afford good cars, my dad and I thought it would be a good idea to fix the car I had ourselves. Unfortunately, the only person I know with less ability to fix a car than my dad is myself. We decided to change out a battery and some battery cables. At the end of the day, we couldn’t close the hood over the “fixed” cables, we lost several wrenches “somewhere” in the innards of my car, and if we calculated our time in terms of what we charged our companies (our salaries), we spent several thousand dollars more than the repair should have costed. Oh yeah, we also both injured our hands and arms dealing with it. That was a good life lesson. From then on, I found a mechanic that I trust, and will have any and all repairs done by him.
