Its demise are the mechanics who are collosal idiots.
e.g. the reason it overheats is because people love to pop open the radiator cap to see inside (no idea why) - then it suffers an airlock in cylinder head which can overheat it.
When it does overheat they replace the original metal gasket with some paper item and dont bother to replace the head bolts because literally everyone says ITNAA MEHENGA?? - PAAGAL HOWAY HO!
add-infiniteum for all parts on the car and you have a perfect basket case,
Its demise was lack of parts availability in scrap market, Remember that only metal scrap market dictates what car can be "kaamyaab" in Pakistan.
