TWO........ 1965 dart chargers I purchased over the years

been driving mopars since and never heard of a "dart charger" After reading the above, the only difference was the color scheme so what is the attraction versus a commando 273/235 hp car?

The only rare item I found for a commando car was a 273 rated ate 275hp speciffic to 66 commando motor. Any info about this?
