D3 I think should definitely be the performance back... maybe the back for all the V8 models. The Base model could be either B2 or C, but whichever one is left out this would be an EASY aftermarket customization opportunity for custom inserts.
I love the idea of customizable inserts just like the different grills for the front today. You can change the entire back end with relative ease along with different back diffusers from the aftermarket and have a fully custom looking rear. Plus GM can change its lights easily for different models.
