***UPDATE***
On a tip, I spoke to Jeff Colglazier @ Leif Johnson Ford in Austin, TX. He advised that prior to Nov. 4th, Ford pricing on the Diesel EngineCARE ESP was $1350. Their mark-up was/is $100, which is the price a friend of mine was able to purchase it for.
As of Nov 4th, Ford has raised their pricing to $1620.

With the $100 Leif Johnson Ford mark-up, it comes to $1720. So, bottom line is you can call him and get the
Diesel EngineCARE ESP for $1720.
In my opinion, based on multiple conversations that I have had with multiple dealers, that is a competitive price.
Once again, be advised...
"The eligibility period for the purchase of a Diesel EngineCare 13 item coverage plan is within the 5 yr / 100,000 mile diesel engine warranty period." If you are outside of 5/100k, it is still possible to purchase this ESP with a pre-inspection, and probably a surcharge.
I tried to be as specific and accurate as I could in sharing this. These warranties are confusing, as are some of the
"I got an ESP for $$$$" stories posts. I hope this is helpful to everyone.
