Bought this car on may 2014. I bought cng vxi in Navi Mumbai. It has been one and half year I am using it. I will mention few points here which are very important for prospective buyer.
1) Space- Extremly comfortable for 4 people. Good and at par with sedan for 5 people and adequite for 7 people.
2) Millage- 14 to 16 kmpl on petrol on highway and 20 kmpl on cng.
3) Maintanice- Easy to maintain. Charges are at par with other brand. I wont say it is cheap to maintain. Service quality is just ok.
