that sums up the story, so either his best friend betrayed him OR the person who actually imported the car.
Those Businessman do not cheat, they only provide cars of all quality, tampering is done after car arrives in Pakistan, the maximum which can be done in japan is repairing a car in Japan then sending it to Pakistan. It can also be traced. so one has to learn before buying an imported car. Sadly most of our fellows don't have information and gets cheated easily by these thugs. we imported a Vitz 5K KM on ODO with one door replaced in japan now 50K plus still running smooth only Normal OIL change.
