Yea, it leaves more questions than answers. It does sound like it will be similar to what Scion did where "the posted price is the price" but the posted price does not have to be MSRP. You would think (in a logical, non-dealer world) that this would make it much easier to comparison shop across dealers. I think it could have been simplier though. My rules:

Dealers must sell vehicles at MSRP or below. The final price cannot include any fees other than tax and registration fees.
Dealers cannot add anything to the vehicle that was not a factory option or a dealer installed factory option (listed on the window sticker) unless agreed to in advance.
Dealers cannot charge "document fees" or other administrative charges as these are part of doing business.
