Thanks all. Obtained the pin and can now see the X price. 
Not as great as I expected. Actually, on our company web site it isadvertised as 0.4% below invoice. Ford's x-plan is way above invoice! 
  
Example: 2010 Limited AWD 
MSRP:  $35,070  x-plan  $33,340 invoice: ~32k 
  
I got already a better offer without any of the official cash backs for less than the invoice. Granted, the dealer might get "dealer cash" that I'm not aware.
