On the looks front Dezire looks pretty bad. With Indigo, its just that people have got used to the looks. Remember when it was launched it looked awful just like the Desire it was an Indica with a funny looking boot stuck at the back.
On rear seat comfort Dezire can seat only 2. The 3rd person will be very uncomfortable given the design of the seat mould. On boot space Dezire is average not good by any standards.
Among the list I would select a Logan. Great on space, good VFM
People who criticize Logan for its looks
take a look at these 2 pics.
and think again ???
