Let me eradicate your confusion:
Only consider locally assembled, PKDM car.
JDMs may be avoided, as in budget of 18-20 lac PKR, it is almost next to impossible to get a neat and clean 2015-2016 model, unregistered Vitz, Passo / Boon, with auction grade at least 4-4.5 / above, with verifiable auction sheet, and fresh import.
The ones already in market and registered, like an year or two old model, can be bought in this budget, but then again, their condition, odometer reading, etc. can be a big question mark, and risks may be involved.
