How does the Z-plan affect dealer markup? Please pardon my ignorance, but I have not used the Z-plan before. There is a local dealer that has their non-Base models $3000-7500 above the MSRP. Does the Z-plan pricing become a certain percentage off that market adjustment? I am not so opposed to paying MSRP because it's in demand, but I don't want to just hand over a bunch money unnecessarily.
