Hey All!
I know that you must be thinking that why I have titled my comment "Still I like this Car - KWID", well this is because I have many times visited to service center after my successful first service completed as it was month of March and then at that time there was no need of Air Conditioner and thus car was doing pretty well.
Later in April when I started using AC the car’s performance let so down that on AC even accelerator paddle stopped working until we switch off AC, whether you keep on neutral the car won’t feel race and therefore I decided to visit service center where they tuned my car and solved that issue, now KWID works fine for me but the major concern is that after that system failure and changes done in tuning of the car I am getting poorest mileage in the segment where it is claimed the best mileage car in this segment, currently noted and re-tuned again resulted with the best of 11.3 KMPL in city and 16.4 KMPL on Highway with no brakes with ON and OFF Air Conditioner.
Still I am satisfied because it is mine now and there is no better option to accept it.
