Stay far away from amnesty cars. Only amnesty SUV's have better resale.
Wait for a genuine buyer. You will come across such ridiculous offers. 10-15 days back I was selling my 2010 City and was demanding more than reasonable for my car just because I wanted to upgrade. But now I'm waiting for new model. Even I was about to give it to @huzaifaa but my brother's mind was changed when he heard from someone that new model of city is coming in Feb 2015. He said better wait for new model.
One fine morning a man(wasn't looking a typical showroom owner, suited booted) came along with 3 mechanics to inspect car, in the end he gave a very good offer of just 11.50 lac. I was shocked. I simply told him to please walk away iss se pehle k mera demagh kharab ho apki aur baatein sunn k.
Another one. A guy called me from Peshawar, was talking nicely. Asked for detailed pictures on viber and all and then I dropped my family commitment just to cooperate with him and in the end he got scolded HARD by me over phone for his ridiculous offer of just 10 lac. Loag doosron ko phuddu samajhte hayn.
Your car is lahore number. This is the biggest turn off for Islamabad people. Post add in sunday jang and dawn, talk to some reputable showroom dealer and it will sell around your demand. Pakwheels is full of time wasters now.
