We made the same interior color change... I had Silver over Black originally ordered, then realized a couple of things: seems like every Z8 is that Silver/Black color combo, and the Red interior is just better looking regardless, especially on the retro-look Z8. Mine should be here in early May, too. As a semi-aside, I also recently saw a Red Z8 and the color just doesn't seem to look all that good on the Z8's shape. Then again, I saw it at night under artificial light (flood lights at a dealership). Regardless, Silver over Red is the best. Black over Red is pretty good, too, but too much of a pain to keep the exterior clean.
