What's custom here? The door, the dash, the glove-box, transmission tunnel, e-brake, and shift boot are all covered in or made out of a high quality leather. The seats are remade with padding added and covered in a higher grade of leather than used for the rest of the interior. The center console was plated in copper and painted wrinkle-finish black. The ashtray was chrome plated. I really like the way the textures come together.
