Buying experience of Baleno is definitely good, it is one of the best hatchback in this segment and value for money car. I have driven it 10k+ and never face any such problem that made my journey bad. Provides very good AC and comfort. Front seats are perfect but rear seat lacks some good thigh support and as it is a hatchback so of course, you will feel very close to its roof. The average of the car is pretty good, mostly around 19-21km/l( on expressways you will get much more) and in city only, you will easily get 19km/l.
The looks of Baleno is really very sporty, packed with 1197cc engine and 4 cylinders which makes it powerful enough for a 5 seater car, and i think ground clearance is enough to drive on all type of Indian roads.
The service and maintenance of this car is very pocket friendly, normally it will coast around 6 to 8k per annum for 10k + KM( if there is no external repair or damage) which is very normal and if you maintains it good than I think not more than 30k for 4 years.
(Hope this review will help you to decide your car:)
