I had this LXI Duo wagon R in November 2010. In starting I did not drive it more. In Five years it was driven 32000 km. But from 2016 I am driving it on an average of 2000 km per month. It is fuel efficient and runs economical on LPG. I commute daily 90 km with it having an average speed of 70 KMPH. It is comfortable in driving and upright driver seat is an advantage. It has an upright position and look. The servicing is not too costly and maintenance price is not so high. Maintenance is lower than other companies cars.
The main advantage is its standtall look, and high driving seat and looks, alongwith fuel efficiency on LPG. Disadvantage is lack of safety features like airbags, and it's a bit less comfortable for long drives, although I drove it to around 300 km in one run.
Overall it's a nice car I have driven it nearly 1,10000 km and still it is a performer. I am very much satisfied with the experience of ownership of this car.
