I have a 2 month old santro xing XL. It's a great car in all aspects, except for the fact that the gears should've been a little more in the front like the Zen. If you're moving to 5th gear,(especially for big people) it's a little uncomfortable as the gear is very close to the body. Also for those who are used to the zen, where you can keep your hand on the gear, in the santro the gear vibrates a lot as if you're in high revs!
That's about it. other than that the Santro is THE best car availble. great power comfort and style it's amazing. I chose the Santro over Zen Estilo and the Wagon R.
Very comfortable, sturdy, good fuel economy,nice high ride height.gear to near to the hips, should've been more in front
