I have purchase I20 elite sports 1.2, in 2016 . After using car for 1 year I m writing this review.
pros-
Petrol version have a mileage about 15 km/l in city and 17-18km/l in highway, but I must say the car is very smooth and steady on top speed of 140 km/hr also. The build in quality of this car is very good, it gives a premium look and feel to the owner, the sound system is pretty good, the lather in car is very good, car is quite spacious and comfortable for long roots, and handling of car is very good as compared to other cars of this range . If you are speed lovers go for diseal version because it has 6 transmissions . Glove box is very cool .
cons-
Suspension of car is not quite that good, I feel it lacks . LED light is not there for rich look. Ground clearance can be increased to 180mm. Air bag shoud be increased for back side also. CC of petrol can be increased.
Overall very good car in 6-10 lac range, go for it. do not hesitate.
