LOVE TO DRIVE CAR ON HIGHWAY

I bought this car in August 2018 , till now I have completed 4600 km , The car is running superb at highway ,no vibration and no lags , 120 km/hr you can drive smoothly ot feeling of such a high speed , I drove it to maximum 160 km/ hour ,it was very stable at that speed also. But in city you have to put ur hands on gear ,not good performance at city which I noticed. Rest all okay.
