I am driving Santro from last September(2001). The experience with car is ultimate. I really call its engine as like of Butter (makkhanwalla) very very smooth.
Later I experienced problems with its Braking I really felt Unsecured driving the car the brakes were not good and also with it jerking while driving.
The service station people recognised the problem and immediately repaired the problem. Santro need very very clean petrol and the service station people requested not to fill the SPEED petrol as there is some problems recognised by these people for the car. SO for JERK FREEE DRIVE say NO TO SPEED.
Santro is a GOOD car to move about in city.
