I have the Beige and am happy with it... but I like the Terracotta also. The elephant in the room is the exterior color. For me, that defines the interior trim color. While some like it, the 'Superman' combo (blue ext, red interior) is not for me, but I'd love the coral red on AW or black.
If you wear jeans a lot, perhaps a lighter color is not the best choice - I fight the blue dye rubbing off from my pants weekly on my beige seats.
My local dealer has a wide assortment of different upholstery colors on their cars - unfortunately, every car they have is white, black or some form of grey so seeing the contrast exterior/interior is not possible.
