I have heard various things about the first generation Constellations, what I want to know is this, some have said the 82,84 and 85 were introduced at the same time 1955, I think this is incorrect, I think the 82 was considered a 1955 model, the 86 was a 56 or 57 and the pink,"Very much desired!" model 85 was made in 58, who is right,???
