I bought this car in 2013. And my overall experience with this car is good.
But as a drive I feel their seats are not comfortable. I started feeling back ache because of driving this car. Now I am putting pillows in my seats.
I would recommend Maruti team to change their seat. I drove i10 before this car and their seats were very good. Even seats of Wagon R is better then swift.
So I would recommend drive this car before buying. Because this thing matter when you drive this car regularly.
