I owned a wagon r 3 years back and I am fully satisfied with wagon r.Wagon r is the best family car with very good mileage and it is very comfortable for family.
3 person can sit on back very comfortably.Best thing with wagon r is that it has zero maintenance cost and if in any case you need any spare parts or any service you can find their service center very easily.
Air conditioning of wagon r us also very effective.
