Just FYI - Ford has cracked down on employees giving pins to complete strangers so you may not get a response.
Honestly, you can usually negotiate the x plan price on your own on most models since they changed the formula a few years ago. Xplan is now around $150 over dealer invoice.
There is no X plan for warranties. I don't recommend buying them if you can afford to pay for a large repair - you'll save money in the long run. If you do want one check the internet sites like Flood Ford - they're usually cheaper than the dealer.
Google "mustang club of america partner code" then use that code at fordpartner.com. You can do a build and price or look at in stock dealer inventory and see the X plan prices.
