We don't want to talk about it, but everybody does.
As a young boy, I recall my father often coming home from a garage and complaining about taking it in for an oil change and getting it back with greasy hand prints and a burnt out light bulb, and when he took it back, the mechanic told him that the car also needed an air filter or tires, or a bla-bla joint.
My dad was very passive and trusting, so he kept paying because he said that the car had to be safe for his family.
Some years later, I enrolled in an Auto repair technician program. I took every training course that I could find, and eventually I came to some conclusions to my fathers car repair challenges.
