Here is the deal with X/A plan. X plan gets you 1% under invoice, A plan 4-5% under. Dealerships will usually not offer X plan on speciallty cars like the Bullitt and Cobra. I checked out a $20,000 Ford with X plan about 2 months ago and it came out to a savings of about $1,600 dollars, pretty substantial if you ask me. Some dealerships will also combine X plan with ongoing rebates saving you even more money, but not all dealerships will do this. A plan is only for Ford employees and their immediate family. I don't know of the companies who offer employees X plan, but I think that Radio Shack is on the list. I would say try to get someone who works for Ford (maybe even in a friendly forum) to get you the X plan pin, I think that they get 4-5 a year to give to friends.
