Mopar Only Shows

I thought it was to make the dealers - sponsors happy to promote their new cars they sell everyday

They have always had a display area for the dealers to show their new product, and since every penny raised by the show goes to charity there really isn't a profit motive either , a great many of the people buying new Challengers are the same people who own older Mopars and they want to do what they did 33 years ago when the show started -show off their cars .
