I think we have a wide variety of motivations in collecting.
Some of us want accuracy in original paint colors, some don't. Some want exclusivity in their purchases, some want a better price. For me, I buy what I like and try to enjoy it. As far as paint colors are concerned, I don't think the light blue on the Packard looks bad at all. I like it. But hey! What do I know? I'm a guy who collects pink and green cars
