I had purchased Baleno Sigma in May 2016. Its an amazing car. Recently, I went to Palampur, Himachal Pradesh and it produces an average of 22.9 km/h in petrol. During hills we usually don't use ac due to ups and down and moreover in hilly areas fresh and cool waves are better than ac. AC was only used during highways. Yearly service cost around Rs. 3, 500 to Rs. 5000/-. It depends if any part needs to be replaced like brake shoe etc. It is now more than 5 years. I have not even replaced its battery and tires are also in good condition. Frankly speaking I have nothing to share about its cons. I recommend all those customers who are looking a car at reasonable price with full comfort.
