superbird77, I went through the same thing for the past few years you are bringing up here. I have a 1969 Satellite Convertible and at the time I did not really care for the F5 green which was my cars original color, I kept looking at a gun metal type metallic silver/ gray or something different than the original color. I also kept telling myself it's a Satellite with a lower value than other b-bodies of the same year and I could sorta give it a custom look. But in the end after looking all over for similar body styles with the F5 color, my mind was made up and I put mine last fall back to the original color and I'm glad I did, I just don't see too many of these cars this color and when it is all finished I think it will be a sharp looking car. One thing I'm doing is also what you mention about the interior, mine was bronze/saddle, that I could not get myself to like, I am going with a black dash, carpet and white door panels and seat covers, since it's a convertible I figured I wouldn't get so hot with white seats.
PS- I did however add black at the bottom like a GTX with a F5 .25" pin stripe just below where the trim goes, this could always be painted F5 to make the whole car the way it was born, I had to do something different, couldn't help myself....
