Oh how I've missed some of the stuff on this forum...
ANY CAR is worth whatever the person actually BUYING one feels it is worth. They don't have to justify it to internet legends.
Personally, I also have no "insider knowledge" on the topic Pickles started. But, I do agree that HSV for sure have been keeping their options open. They know perfectly well what the GM Powertrain closet contains, but, contrary to the thoughts of many an internet commentator, they are a successful business that only does what it NEEDS to do to be successful. As soon as a business starts caving in to the demands of people that often aren't even going to buy said car, they might as well shut the doors and find something else to do.
I believe they will release an LSA powered car as a limited run leading up to VF, based purely on how I believe they run their business.
