Lots of cars came with combination white and black interior. This one is from a '69 and needed some repairs but you get the idea. I think it looks pretty sharp.
I have the other Turquoise '68-S (notch) and it actually came new with the combination black and white. It was changes some time ago to all black but I had the black and white in my red '69 (pictured on page 2). At first I didnt like it but it grew on me. If I had a choice I would without a doubt, go with the black and white. Most everyone has black, it looks good but the combo black/white is really different and looks great.
