Bro i am not saying that you CAN'T find a good car, All i am saying is that you won't be able to verify the auction report if you opt for a car which was imported in 2012 or before. Currently dealers can only import 3 years old cars thus the oldest model you can freshly import is 2010, All the older models are imported before or at max 2009 model taken out of port by muk mukka. As far as my market research says a good 2009+ model Vitz starts from 10+ and can fetch till 13.5 (depending on condition, grade, color, features).
To be honest i have yet to come across a "Honest Car Dealer" I say this with all due respect to everyone and please no offend intended as that's my own opinion. One of the best people you can't contact would be Sharabi (Shahzaib) you can search Facebook for JDM Imports, Atleast he is honest in what he is giving you. He currently is dealing in LC's mostly so he seldom have choti moti cars for people like us, He currently has a Move for sale and he has two Vitz on way to Karachi (Reaching 25th of this month) both of them are in range of 11'ish though and are 2010 models White color. Two another dealers on Khalid Bin Waleed road are Liberty motors and Burki motors both have good reputation for getting good cars but they hardly budge from their asking price but atleast their cars are very nice.
For past two months i have been roaming around from one JDM dealer to another and nearly went for a 0 Meter SWIFT but due to share pressure of my wife (who was/is hell bent upon getting a JDM) i ended up giving token for a 2010 Vitz on it's way to Karachi, Insha Allah will have it by next week (If i find the condition of the car as per my requirements) else i will be back to drawing board myself.
