It is the new Santro Prime. Two versions are being offered. One with body coloured bumpers and the other one with black bumpers.
The one with black bumpers is the all old Santro Club with a few cosmetic changes, and the same trunk space. And its price is a lot lower than the Club. On the other hand, if you go for body coloured bumpers, the cng kit covers the whole trunk with no space, like cultus and all.
So its upto you to chose between body coloured bumpers and a bigger trunk space.
