I have a 2005 santro Xing xp. Bought the second hand car @1.87lac two years back in 2012. The car was in very good condition without any scratch and 25000kms done.
And was giving overall a decent mileage of 13kmpl in city and 17kmpl highway drive. Recently I had to change my clutch and flywheel @7k at authorised Hyundai dealer due to clutch hardness and drop in mileage to 11kmpl in. City.
The good news is the car is giving a awesome mileage of 19 kmpl in city(need to check in highway) not sure how long it will gi’ve this kind of mileage. Not sure what exactly went right to give this kind of mileage for a 8 years old car. Also not sure how long it will stay like this.
