When I was the fleet manager for my police department we had to pay $22 for them to leave the body side moldings off the car to accommodate decal placement. The cost of police Tahoes vary from state to state. Most agencies buy them via "State Bid or Contract". Dozens of dealers compete for the business by submitting a sealed bid to supply cars for the upcoming contract year and the lowest wins. It may even be a out of state dealer. Then any agency withing that bidding state can buy from that dealer. Local dealers may match that low bid offer.... but that is rare. When you are buying 2,000 Tahoes at a time you get a MUCH better price. You can get the unit stock from Chevy wit the PPV/SSV or fully outfitted with lights & siren.
