It seems pretty easy to me, though it's not the most convenient:
If you don't want to pay above MSRP, then wait. Please - I'm not trying to sound like an @$$ or be a jerk
They can't rape you if you don't let them. Unfortunately - GM can't do anything about what the dealer tries to sell the car for. I encourage everyone to wait, because if some of you let those dealers take advantage of you, it's not helping the cause of the Community. If it doesn't sell at their mark-up, they'll be forced to lower the price, or just not sell the car until the market is more saturated. I know no one wants to wait (neither do I), however, we control the market. It's hard when it's such a great car :( Everyone will have their chance though
