There's a price to just getting up and building another car, let alone keeping the same chassis and moving to another class. I think that's whay there has not been this ... exodus. I personally have too much invested in the Civic and would not consider changing car/class until I feel I have gone full circle with it. In Kirk's case, he had a clear opportunity to change class given the current structure... IT is NOT going National. Should I have been in the same situation, I would have done the same. So, the out-go rate from IT may not big at this point, but over time, folks who are passionate about the build/ease/dependability of IT and wanting to compete at a true national level will be disappointed and will need to move to another class, sadly.
