First of all I would like to clarify that there is no connection between indica v2 and indica vista except for the name.the body shape is entirely different.it has 1.3lt fiat multijet engine and also houses a fiat gearbox.
I bought vista qdj aura one month back.excellent car, outstanding space inside.having driven 900 kms, im able to get a mileage of 16 in city which is very good(before first service).hope it may go up to 18kmpl after the services.the space inside is same as that in verna, sx4.very comfortable leg room and head room.
There is an issue about the instrument mounted in the centre, but I didnt feel that its problematic.it has a power of 75horses and pick up is good. engine is very silent and ride quality is also good.many features like steering adjustment and seat height adjustment are present in this car which are not there in swift .overall this car gives huge value for money.it is better than swift in many departments.if u r planning to buy a swift, test drive this car once and u will learn for yourself.
