Ahsan, so you have bought a Khyber? Yaar honestly speaking I would have gone for a over haul thing... if i want to keep this car for few years. Unless, i found some sort of a new engine, and we all know chances of that are very limited specially for a Khyber.
aur wasey bhi... changing of engine number at eto office is hassle. and what about resell of such car... guess it effects that too.
