I drive the black diamond, hardtop, tow, sas and love it. My opinion is the Black Diamond is the most underrated package produced for the price. But we all know the "opinions are like ....." everybody has one.
I purchased my Black Diamond SAS mid about a month ago. Certificate for $800 off pre-loaded and they applied. Agreed upon term was, once sale complete between dealership and FoMoCo dealer would cut me a check for $1899. They followed through. Holding it in my hand right now. Took about 3 weeks.
And there is still the used car market. I doubt we would all go direct to consumer when getting rid of our old rides. Certainly there would still be used car lots. I could be premature with that guess though.
