We purchased the Wagon R without initially planning to, after we could not get the Swift for many weeks although we had booked right at the beginning of the booking period for Swift. We are very happy that we purchased the Wagon R as it totally serves our needs.
Firstly, Wagon R is a easy to drive and park in city traffic. The fuel efficiency (in congested city traffic, mostly with AC) is 13 kmpl. The use of inside space is amazing and we seem to be able to carry our entire house with us inside the car. The seats are not so low as in many cars, which means that in the Wagon R it is easy to get in and out, and not tiring to sit during a long drive.
We have purchased the LXi version which I think is the best value for money - we did not think it was worthwhile to spend on the VXi as the later model provides features we did not really need (tachometer, front power windows, rear defrost).
