I am an ASE certified Master Truck Technician (I work on trucks and heavy junk).

The theory us professional mechanics have about partsmen is as follows.

If your daughter comes home with a man she has declared as "the one", and he is a partsman, you can feel safe.

A partsman doesn't know what he is looking for, and doesn't know what to do with it when he finds it.

Oh yeah, they like to put a little screwdriver in their pocket protector and try and convince do it yourselfers that they are a mechanic.
