Yes and thats not much. Pays for maybe a Production SE, Lease admin or sales coordinator and part of a Sales Manager.
Art it depends on how many reps whats the comp plan etc.. Do any reps voluntarily give back salaries when they sell little or nothing one or two months out of the year? I think not, the pad also covers these inevitable down months.
If you want to be pure about it. Compare a straight commission position with actual dealer cost. I did it once and made the most money I ever made. Im on a hybrid plan now thats 90% profit real P&L now, the good months are really good the bad ones are really bad but how many reps would accept a true profit only based position?
