My experience (and having friends in the business) has taught me that there are 2 Invoices.
One is the legitimate factory invoice that shows what the dealer actually pays for the vehicle. Customers are never shown this one.
The other one looks legit, but has massaged numbers to build in some additional profit, sometimes over and above what dealers get through factory incentives, kickbacks, and/or other rebates. If buyers go by this one, they basically get bent over . .lol
When i bought my F-150, it was almost 12,000 off factory invoice (the fake one), but I knew the game, and knew the real invoice amount, so got a fair deal, and the dealer STILL made money... SO that tells a person how much profit there is in vehicles
So, when you say " invoice", is that the REAL invoice or the "other one"?
