It probably made sense to swap it to the E67 anyway given the CTS-V will be sharing (more or less) the same motor and it's always run the E67.
I also agree with what you are saying on the prepared Corvette comparison, I'm sure there is a number of cars (and trucks!) owned by people on this forum who will out run a new ZR1. I think it's more about the prestige of owning one.
The CTS-V's look nice, but what size wheels are they?, they look at most
to be 18".
