Plum Crazy or Citron Yella?

You started off with ‘two demons in a junkyard’ which usually means the cars are missing major components. No mention of how long they have been in the junkyard either. Also no mention of if they have drivetrains nor what the drivetrains were/are. We are not fortune tellers so suggesting the one with the larger engine wasn’t at the top of our minds. Your question was about colour which is what people responded with input on.

It’s your $$ so buy the car you want to own! If your looking for a conversation generator pretty well any classic car will do that regardless of the colour, engine, transmission or the lights. The fact it’s a 53 year old car already makes it ‘rare’. Please don’t equate rare to $$ though.
