We have the same markup and margin no matter where the parts come from. Do you tell your customers where their other parts come from? Then why should you tell them stuff is coming from the dealer. They are just another supplier. Why should you make less because the car needs special or rare parts or fluids. Also stop using the dealer for domestic parts. Try Universal Lift, Rowerdink, or for Chrysler try to find a wholesale dealer with a parts warehouse like Milosch in Michigan.
