I'm not saying the market is determining a $100K tag, I'm saying the market will determine if a $100K tag is viable. That's exactly what was at work when the Vette's tag was cut $21K. No dealer can force anyone to pay 'adjusted' pricing.
OEMs do the very same thing with 'launch editions' that cost $5K or $10K more for the same vehicle. There, the market generally says that practice is viable, because those sell (and commonly; sell out).
I'm only speaking my mind; personally I'd never pay a 'market adjustment' but then again, I never buy first-year vehicles anyway.
