I prefer black leather too. I have the sand with black accents, black exterior, and it's quite nice. The only problem I have is the dye (blue from jeans?) transferring to the sand. Always having to scrub it off.
Tinting your windows helps to prevent fade.
Which color? Sand or Black? I prefer black. My husband prefers sand with black accents. The exterior will be black. We live in a hot part of the country, but that is not an issue. I've had black leather before and liked it. Any problems with fading?
