I got my Brio in June 2012 and completed just 6000KM on it. Like all I was confused to buy it or not, but Brand name is what made me buy it. It is my 1st car and I love it like anything. Started with a mileage of 11-12km/lt (full tank to no of km run with A/C) and slowly it picked up to 18-19 (without A/C) and on highway it gave me a staggering 23 (470Km driven in a day with and without A/C thought the journey - average speed 85Km/Hr and did not drive above 90Km/Hr). I am too happy with the mileage.
The interiors are excellent and comfort level is high. The small car is all power packed and has high acceleration. Only thing I dont like it its boot space but still it worth the money spent. I have S(O)MT model with all safety feature of ABS and air bags.
Definitely a 5 star to it.
