Paying an additional $26k excise tax, at a minimum + the cost of a CTS-V in Europe is a big argument in favor of going for a Northstar swap. However even if the mechanical obstacles to a swap can be relatively easy to overcome, coming up with a PCM that is happy with a Northstar engine and 5L50e transmission in a CTS chassis may be a very difficult problem to overcome.
