Having driven this car for the last 3 years and more and clocked nearly 20000 km, faced no issues in terms of driving and performance. The average of this turbo engine between 19-21 is well appreciated if you drive below 100 kmph during highway and in city traffic it reduces to 14-15 kmph.
The average Maintenance cost is 5-6k per year. The only cons I dealt with till now are paint quality and windshield wipers
