Hyundai Santro Xing eRLX is an average car used by middle class family. I have 2008 model with an average condition. The fluent problem with me is that the car may stop at any instance even while moving on the road. I have a gas kit passed but even then I have to use petrol for initial starting every morning as it does not start on gas. It even gives jerks while moving. It gives me mileage of 17 or 18, it varies with respect of way of using & keeping it in what conditions. It has a positive point too, that it has a wide space inside the car.
