I own a wagon r abs model. it has been over 6 months I am using this car. I dont have any complaints for this car. infact if you are low on budget of around 5.5 lakhs. you can blindly go for this car. the first advantage is that it is of maruti so no problem in the service. second is that it is packed with all the necessary features which are needed. although the music system is not good when used at high volume but at medium sound, it is quite impressive.
When ac is used, the mileage is around 17-18kmpl and without ac it manages to provide 19-20 kmpl which is very nice. also it comes with the airbag and the abs which is very much necessary and really very helpful. even if you hardbreak the car at around 90kph, due to abs the car doesnt skids which is very impressive. I am happy with my car.
