This is a good enough bar for me to take a chance on someone. If I'm satisfied with the result... I proceed. My "car guy" has a track record of saving me from over-spending on things that don't matter. I don't have a good enough reason to try someone else.

2. simply possessing the skill and knowledge to assess the work yourself (but lacking the time, energy, or other resources to do it yourself)
