I purchased Maruthi wagonr on 1st jan 2010, till that day I am driving this car almost 13000 km already ride.
I found this car very useful because of its space available inside secondly the passenger in the rear seat also have a good view of the road because of the little elevated back seat. The more attraction I found is the folding of back seat make a comfortable platform a in the back, like if you are planning for a long drive you can put a bed over there and have a comfortable sleep (this might not be possible if you have CNG fitted.).
Some say, the look is not very good but I found it very good looking especially if its a WHITE color.
thanks
