Where can I find Dealer's cost from factory on a new car?

MSRP & Invoice price are readily available. No one should pay MSRP. Invoice price isn't what the dealer paid. So I'd like to know where I can find what they paid the factory so I can have better position when bargaining.

I'm looking for dealer cost for a Honda CRV LX 2WD,
Update: Edmunds.com, Cars.com, Yahoo Autos, kbb.com, nadaguides.com give you invoice & MSRP, but do they give you dealer cost from factory?
