I drove vijay's new diesel indigo and here are some observations:
a) Overall the price came to 5.23 Lakhs and for that price it is a great deal.
b) The leg space in the front is really good and the back seaters can also be comfortable.
c) The body is good and i even liked the almost 90degree opening for the doors.
d) When you drive the same, you dont feel like you are driving a big car - 1. A slight noise probly because of diesel 2. Power when you initially start is less than that of a santro.
e) Looks great from the back. From the front, it is just like a indica. (probly they didn't want to risk the design). from the side, it has the looks of a sphinx - two cars merged into one. (so dont look at it from the side).
f) Great boot space - i have never seen such a big boot space.
So overall, they seem to play on the price rather than on features.
