Who knows. Maybe the dealers who told us that they don't use them didn't want us to see invoice pricing.
I'm pretty sure they can print them out at MSRP. It depends on the pricing code they put in. A Dora is just acknowledgement of a receipt of an order from Ford.
I get most dealerships are just not use to handing them out.
My current dealer sent me "Order Summary Sheet" which has everything a Dora does but only list MSRP (As my deal was cut at a $ amount under msrp not over invoice). My Saleman called it a Dora but it does appear slightly different than my last Dora.
My Gen 1 was cut at $500 over invoice and that dealer sent me a Dora at invoice with +500 on it like Brian has.
As long as the dealer gives you an order number and their order code you can track your order.
