Yanno, one could make a pretty nice collection with just Colonnade coupes. Buick GS, Pontiac GTO, Grand Am, and Can Am, Olds 442, and Chevy Chevelle SS, and Laguna S-3, and Monte Carlo.
Great work on this GS.
Looking at those, it makes me wonder if the casting was originally for aircraft, and the "reversed" side would actually be the outside face in an aircraft application....?
