mmmmm your old car looks great!
Fox red is not a bright red. It's more like an rusty brownish orange/red.
Pictures are awful to tell what a color shoudl look like, especially Fox Red. Having seen the old cinammon in person, I'd say Fox Red isn't too far off, and certainly closer than Bamboo, as well as looking more unique. In case you can't tell from my recommendation, I have Fox Red, though my paint is Sparkling Graphite.
