I remember a few years ago the Commanding General at Lejeune put the kabash on at least one big dealership in Jacksonville because they were ripping off Marines. It was too easy - - piles of 18-25 year-old Marines would return from deployment with a wad of combat pay and they didn’t really care to waste time shopping or making the best deal. They just wanted that flashy pickup truck TODAY! Naturally, the dealerships took advantage. Once the general got involved, that gravy train came to an end real fast.
Many of the businesses that fed off the bases there and in Fayetteville were on the seedy side. Some still are. Caveat emptor.
