I might take one of those with wider tires, platform and extreme Z07 aero.My prediction for a suspected Grand Sport C8 is exactly the same as they did for the C7 GS. Same engine as the SR in a wide body with upgrade in suspension and some pretty bells and whistles inside and out.
If it is in and around the $10000USD base price difference of the C7, I might consider it for a better track machine.
