I haven't seen anyone mention carbon fiber, it's either Figured Ash, or Dark Ash. Has anyone had any experience with carbon fiber in the Model X or the S? I thought it would look great with the Midnight Silver, black seats with black headliner, and doing matte Xpel on the seat backs. My second choice would be Figured Ash, with matte seat backs, followed by Dark Ash, and glossy Xpel. We have 6 days left before changes require $500. What say you all? Thank you for your responses in advance.
