The model is a Corvette ZR-1. The RPO list and build sheet don't have "Corvette" on there either, but that's still what the car is.

You could say the "Corvette" name is just a marketing thing too. And I suppose it is. But that doesn't make it meaningless.
That said, I don't think the dash is a biggie unless we have both gens on the board, then I suppose it could add confusion if someone doesn't reference the model year.
