My experience with Alto 660 2007 shape.
Very Noisy....Very Slow....
But then again , how one measures the performance is very subjective... if you are driving a mehran atm, you will just love all the 660s because they are softer and loaded with features. You might even em like if you're currently driving Local suzuki alto. You'll hate it if you're used to driving Hondas & Toyotas.
I think they are a good alternative to the local manufactured Mehran & Alto. You cannot compare them with bigger cars..Even cultus.
But then these are small cars which are easier to park & drive.
