I have santro since 7 years. I must say it is the most reliable and maintenence free car. Till now I do not need to change any part. I just service it once in a year. Its mileage is approx 10 km per litre, which is little bit less. But it performs good in city and highways both. Its interior and extreior both are good. Leg room and bootspace is less, but same as other cars of this segment. Over all I think this car is best in its segment. Hyundai should not stop manufacturer it.
