Santro is an Excellent Car... no question about that.
There is only 1 problem (back seat leg space), thats it I believe.
When I bought it, I wasn't expecting that much quality and durability from this car. (I bought it Cuz once I got a chance to drive Santro Plus (my cousine's car) and I was amazed of It's drive, but didn't like It's shape and when they introduced new shape, I immediately bought it.
Its been 3 and a half years now, 82000 plus KMs done and I didn't get a single issue in it (Thank God).
And after Toyota Corolla I am also a big fan of Hyundai Santro. V
