Ive been using this car for about 2 years now .Everything seems to be working perfectly.Here Im am talking about the lxi cng version of the wagon r.The company claims that the k 10 series engine delivers a mileage of about 20.5 kmpl and about the same on cng usage.Well I occasionally used petrol while driving, but Im sure it give a pretty good mileage.
There had some issues with the tires, As 3 out of 4 tires got punctured .hence we had to replace all of them.
Overall its a good family car, with decent interiors and its quite spacious.Although it might lack in design as the whole vehicle looks like a box on wheels .I must riding this vehicle is quite a pleasure as it portrays good handling even at speeds of about 125km/hr.In my opinion in 4.2 lacks its a pretty good deal.
