Alto 660cc will be launched in 2018 or later. It might replace Mehran. (But who knows, Suzuki might keep producing Mehran alongside Alto)
I have seen new Alto 660cc JDM import on the roads of Lahore. Look of this car is not that bad. People just get used to new looks. Look at Wagon R. When it was launched, majority of people were blabbing it's an Ugly car. But now it has become a hotcake.
