I worked in a Camaro business from 1983-1997. Initially we saved sub frames from our parts cars. Then we only kept disc brake sub frames. After about 10 years or not selling any of them all of them were discarded. We sold a few pieces off them but never a complete frame.

They are heavy, cumbersome to store, difficult to move and expensive to ship. If you need one $150 is a fair price.
