From the starting guys to be very honest the quality of the car is top notch whether it be interior as well as the exterior.
Coming on to the engine the petrol model of Swift is quite responsive than of the i20 and swift has better average and better response.
But its not that bad as compared to Swift's motor but yes the handling and the ride is better in Swift it is a little less in i20 as compared to Swift.
All in all it is a little little costly than Swift but yes if you want to buy a i20 then you should go for it because it has them to me I'm interior the quality of the plastics is top notch exterior looks quite excellent and yes Hyundai have managed to build a reputation of comfortable cars and reliable cars.
