I am driving the Car since 1990, I have never experienced with driving with such a worst car. The Kwid Climber AMT is giving only 12.5 km average in Goa, if you drive in a big city like Bangalore, Ahmedabad etc. then I am sure the mileage would be 8-10 km/ltr.
There is also problems in driving like gear problems, pickup problems. If go through interior then you get everything is cheaper than others vehicle. Better to buy any vehicle other than Renaults Kwid Climber AMT
