avoid carborator, because of expected CNG problems in future.
EFI car will give you better drivability thus comfort. consider the features of Cherry QQ, power mirrors, power sterring, power windows, EFI engine, no overheating problems, good design, better suspension compare to Mehro and Alto (which is like jhoola in rear, no offense to its lovers wrote just for info).
my request to all please don't follow others just buy those things which is attractive, comfortable, technologically advanced. which will kick out the companies with 1970s technology solely for our nation (Pakistanis).
The choice is yours.
