Nano XT- 4yrs, 26000 km done

I bought a Tata Nano Twist XT in 2014 June. Till now completed 26,000+ kms. Mainly used inside Bangalore city, the occasional highway runs in 300 km radius. What I like - 1) Good Average - 22-25 kmpl on a highway, 15-18 in the city. 2) Spacious cabin, high seating which gives a good view of a road. 3) Low maintenance cost- 4th-year service cost is just 2000 Rs. 4) Superb AC and good 4 speaker music system 5) The steering wheel is light. Can operate with a finger! 6) Easy to drive in crowded streets and easy to park. What I dislike - 1) Poor build quality 2) Engine noise inside the cabin 3) Feels unstable above 80kmph speed. Although I have done 100 kmph :) 4) Clutch pedal and gearbox are bit cumbersome. But I got used to it. 5) The suspension is poor, even small potholes can be felt inside the cabin. Overall I am happy with my Nano, it is a good vehicle for city usage and good value for money. I knew the limitations of this little wonder before buying, so expectations were also low. Planning to buy a new SUV range car next year.
