Yeah, I agree that diamond stitching can be over done. We aren't putting it in the console or the headliner.
Oh and Rodger, I was looking at the two cars you mentioned the other day. I think Mulvey's interior had the other style of rectangular stitching in Ferraris that I can't describe very well, it looks killer, but didn't want to copy that idea. As for the Roadster Shop's, I saw that and thought they really nailed the look I had in my mind. I was even planning on red inserts, that is, until we decided on the purple
And that brown color from the ferrari would look pretty classy in the car. As it is though, our stylistic goal was classy and sinister, so diamond stitched areas in the seats and door panels will be suede with red stitching. The headliner will be suede, and the rest will be black leather, err "imitation leather" since it holds up better, and we don't want wrinkles after a couple years of driving it around. I really hope it all comes together well. I'll try to get some pictures and sketches up for some input, because if we've got something too gaudy looking, please, try to stop us.
