There may be some work required on your part to put some of the electrical systems back to stock, as the vendors who typically debadge PPVs back to public use, typically cut out the police equipment, and to not necessarily put the electrical systems back to stock. However, once put back to stock, I see no reason why they would not be good resale candidates.
