As a consumer, I'd like the car to be priced "as reasonably as possible". As a Corporation, GM will price it "suitably", respecting development costs added to parts and production costs vs. planned volume vs. expected demand (considering a likely 16-month-or-so build cycle).
All this chatter of $70-80-90+K pricing simply is speculative...and unfortunately could be "encouraging" to a higher-than-necessary final figure.
The car will "simply" cost what it costs, to purchase. The final decision on that Base figure is GM's decision...and theirs alone. Let's not "encourage" a price that is unrealistic, in either direction, but particularly one that is too high...
