This is an interesting video on a side-hustle that I used to have when I was in college. Basically, I would go to the junkyard with a few specific parts in mind. Find as many of them as I could, and then pull them for resale.

In this video I discuss the advantages of having a junkyard parts side hustle. 

I also discuss some of the parts that I have focused on in the past, and how I determine whether a part is worth picking or not.
