Contrary to the size it has ample boot space. Smartly designed, no matter you are on driver / passenger seat, its way more comfortable than alto / zen / 800. I am 5' 11'' and I felt quite comfortable inside. But the boot space is small and you can hardly put in a laptop bag or a small suitcase.
But for indian roads, where traffic hardly moves above 50 in peak hours this is the car to go for :)
