Old saying: If you have something (anything) to sell, if you advertise it properly for a reasonable amount of time, and it does not sell, it is overpriced for your market, or no one gives a c--- about owning it!!! so tru.
I see car prices in general ON this site andFBBO, Mopar facebook sites, in general, reasonably priced. I see them pretty much always priced somewhat higher than what I would give, but everyone seems to have to have dickering room. And too I have lived in Missouri the last 30 years. Car prices out there, are lower than for projects than a lot of other states.
Used parts. Remember there will be members on here wanting sell of unneeded parts, and they have no real idea what they are worth. Like the newbie taking a load of parts to Mopar Nats for the first time. They take a lot of junk that is worthless, and what they take that is worth having, way overpriced.
lastly: Anything you get for your car and parts over the price of scrap metal, IS salesmanship!?? ha
