I'm not a salesman, but A plan which is the same pricing as Z plan is one of the Ford tiered pricing systems for employees and immediate family. So you have to qualify for one of those. It's literally a code I think. Also, dealers can simply say no to these plans, mainly when a vehicle is new at launch and in a particularly heightened state of demand. I used to get Z plan before my Grandpa died. WHen I bought my MK3 FOfo, I think I got C or D plan through my ad which is one step below A/Z. Technically anybody is eligible for X plan, sometimes if you ask the saleman for it they'll just give it to you.
