COPO. For Chevrolet muscle car fans, those four letters add up to the Holy Grail. Images of '69 Camaros with 427-c.i. engines, and Yenko Chevrolet modified Chevelles and Novas immediately come to mind.
And yet, not everything labeled with that legendary moniker is a quarter-mile terror. COPO actually stands for "Central Office Production Order", and many fleet and ordinary vehicles were built through that system. They were generally ordered as a group, and they usually had some little thing that differed from the dealer order guide.
When you think of limited production COPO Chevrolets, the Citation might not immediately come to mind. But this is a story of a limited production, special order COPO Citation that you probably haven't heard anywhere else.
