Well, the good news is that the prison buses spawn near the La Guardia and Rikers area of Queens in the Wii version of D:PL. I took one and brought it over to Ray's Auto Shop at La Guardia to save it into my roster. Now the bad news is that I can't store it for some reason. So I stole another one and brought it back, and then the game told me that I already stored another (which really wasn't stored since it didn't show up in my list under Commercial vehicles). Can anybody help me out with this please?
