I don't see how unless you are used to paying a lot for LOF/Rotation...so...no disrespect intended...but, it BEGS the question...how much did you pay?
and please state USD or Canadian (I'm guessing in the $150 USD range with the additives)
30 years ago when I was writing Service for New Car Dealers, we had "Spiff" programs.
A supplier would offer to sell the Dealership "snake oil" stuff. The Dealer made a hefty profit from the sale of this crap...and we Service Advisors got a $10 spiff for each package we were able to sell. Some package Spiffs paid more...much more. The cost to the customer was out of line but it covered the mark-up and our spiff. Spiffs pretty much came to an end in the late '90's and by and large Service Departments at Dealerships have cleaned up their act.
But with all due respect...
it sounds to me like this Dealers Service Department is still playing 'ol Skool :banghead:
