I think C8 would be the best barometer for what GM could do with interiors at different price points. Look at the material choice differences from 1LT to 3LT, plus all the color variations and 3 seat choices. GM is able to make the interior go from fairly plain to what I would consider to be too far out there by offering a wide variety of material and color choices. Pretty much what BMW and Mercedes do too. At the relatively low volumes of Corvette and Camaro, there will not be structural differences in the IP, center stack, or console.

For full-size trucks like Ram with a couple hundred thousand units produced, or Silverado / Sierra that are that much plus tens of thousands of utilities, you can include structural options that eventually pay for themselves. Not for cars that sell in the low 5-digits volume.
