When to decide to part out...

FABO I have a great looking sister car that came with my 1971 Duster. She is a 1974 Dart Sport. I'm not too sure what to do with her. Sold the Dual Snorkel scoop this week (Yes It has a Factory Dual Snorkel so that informative thread might want to talk with me because this 74 has a factory not added scoop). Regardless at what point do you folks find it beneficial to part out versus trying to sell it as a rolling chassis? It's not a money thing more like a trying to sell or drag it to swap meets thing.

New to all of this,
Dale
