can it sell it for parts here?
Yes you can sell it for parts.
Yes, you can put it up in Garage sales. Follow the listing guidelines.
what price should i set ?
You don’t need to set an asking price in Garage Sale section
I have no idea about the asking price. Should sell 10% of your buying price. If someone might consider it. That is my understanding. It is up to you. Garage sales is for negotiations and not fixed price.
