I voted for Cardiff Green, though I've ordered Savile Silver with Saville Red Nappa interior. What I really wanted was green with tan interior, but at my Nappa trim level Green only comes with Black, and even if I could get it the Vanilla Cream (?) is too light. I debated Green w/Black Nappa, but that Red was calling to me, reminds me a bit of the 64-1/2 Mustang.

Black (dark grey) seats w/suede so not the overwhelming redness of the red seats with quilted (though red interior including red seats is also one 64-1/2 Mustang combination).
The test-drive was Black w/Red Nappa, which looks really nice, but Black not really a good car colour for me. They have a lower-trim Silver on the lot with their name on it, and the Silver looked good. Not an icy silver like some, more a grey-ish thing.
Don't know when I'll get it though, could be forever but it's only been on order about 5 weeks.
