XUV 500 : Superb car to buy

It's superb car. The design and features are extreme. I don't understand how people are measuring the mileage but this car gives a mileage of atleast 16.5 in city and about 20 on highway if driven at 100 km/h. The maintenance is normal (not very high as said by other reviewers). It's a perfect match of power and features. I have driven it at 180 km/h and still felt the car to be very stable.
