I personally used this car its performance is worst. I am not saying it for all the cars produced by hyundai as I am big fan of i20 ; fluidic verna and my first car was also from hyundai i.e Santro xing. There are several problems in this car is that my model was on petrol so its mileage was very bad Rs 500 petrol was burned in 5-6 kms and its ac is also not strong as in other hyundai or maruti cars. I do not know that this problem was only with me or many people are suffering or has suffered from it . So I sold it @ Rs 3 lakhs I only used it for 2 years. Right now I am using maruti swift it is damn good car its mileage is awesome and its performance is outstanding.
So for me i10 is not good as other cars of hyundai and I personally recommend to go for maruti suzuki cars because of its mileage and performance.
