Oddly optioned cars and Dealership demonstators?

Wondering what kinda wierdly optioned mopars all you folks have come acrossed in your years. Dealer demonstrator cars are some of the oddballs. There is a 68 or69 dart in my area that is a factory yellow, 4 door 4 speed 318 car. The guy who has it says it was a dealership demo car. it now has a 360 in it though factory 318 long lost. owner saved car from crusher

So oddball stuff arrived at dealers near the end of the production year- worked summers in 1968 and 1970 at a Dodge dealer in Baltimore- stuffed whatever was on the shelf into cars- many of theses "weird" combos may have a late production date...
