Hi I’m new here. I agree I ran into the same problem when I first bought my 2017 Grand Sport. The parts guy couldn’t even find the comp seats in the GM catalogue which was funny because I know in the GM parts catalogue for the Camaro, you can buy competition seats right out of the catalogue for that car but for some reason nothing for the Corvette… Then he came up with some ridiculous numbers like it’s probably gonna cost me at least $10,000 per seat! to get these! I was like geeze! What am I buying seats for a Lamborghini?? Lol
