If the Ebay listing is correct, this 300C sat at a dealership unsold until 1990, when they took it out to play around, stuck in a crate 472, backed it with a race 727, and then they parked it in 2009.
Since it's claimed to never have been titled, and the MSO is missing, it's close to being something to avoid... smells like a problem waiting to be discovered the moment you take possession.
But that hemi.. hmmm.
