as far as iknw, the amenesty schemes vehicles are mostly running in that cities from where the owner is, means he cannot bring his car to other city , because the government says that this scheme was ghair kanooni...government says to FBR to seal the cars (which is not easy) so by that every one is selling its car, and no one is buying that cars easily because kal ka, or hukumat ka kch nhe pta lagta...ivill suggest you not to buy it now...
THIS WAS MY SUGGESTIONS, AND WHAT IVE HEARD THAT WAS, IF IM WRONG ANYWHRE PLEASE CORRECT ME..
REGARDS..
