Dealer invoice?

Now that we know the MSRP...anyone want to take a guess at the dealer invoice for the various models?

Isn't it usually around $3k cheaper than MSRP? I've never paid MSRP and I ain't starting now! I think I got my 2000 Camaro SS for about $300 over dealer invoice. I'm not going to get it the first year anyway so I can wait. I'll also order it directly from the factory again so I get exactly all the options I want and pay for none that I don't want.
