I have built, ordered and delivered a 2018 Z06 2LZ. My seats are not embossed with the Z06 logo? When I built it the pic showed the embossing. I have searched and found no special code which needs to be assigned to have the embossed seats. I have also put an inquiry with GM/Chevrolet (no answer yet 1 week!) In addition, I have found several 17's and 18's (Z06 both 2LZ and 3LZ) with and without the embossed seats.
