This from Dennis McGuire, Jr;

Yesterday I went past this place on 43rd St in the Stockyards that does all the lights and other small modifications for city vehicles and noticed two 2012 Ford Explorers. Both were painted black over red with a gold strip between the two colors. They’re obviously for the CFD. I talked to Jim Regan and he confirmed that a total of seven are on order and they are¬†all 2012 Ford Explorers.
