The Dodge Diplomat was built from the 77 model year to the 89 model year. That's just ONE model car. How many of those do you think were equipped with the cop car package? Now, that would have been police, fire, EMA, boards of education, military and on and on. and that's ONE model. They were also available in vans and trucks. You don't think a million were made? You better think again.
Police package was not available to the general public.
