If you work in sales at the dealership you know the daily grind of selling cars then having the finance manager skim your profits out of the deal into the back end making your commission vanish.  How about the mysterious appearance or repair orders or dealer costs that further nickel and dime you into the flat fee on each transaction.  You do not have to take it any more.  They cannot take more pack than permitted in the payplan.

You have a written pay plan and the dealer has to honor the wording and the spirit of the agreement.  They cannot reduce the commissions by unspecified overhead, that's why they have a pack.  Get the pay plan and make them comply with their own written words.
