I have allways liked the Plum Crazy '69 Road Runners , and I know that Dodge had the same thing with another name. White interior might be a good idea in that at that time most of these cars had black interiors. Even in scale that starts to make the model look very dark. I think like Bill said, do what you like and can afford at this time. The lighter colored wheels or mags might help make the model standout more. Please post pictures and good luck with your build.
