I have purchased nexon xm petrol model few months ago and i have done 8000 km approx. The car is very good. It is giving me a average of city - 15, highway - 19-22 depending on the driving condition. I got a good discount from the dealer. The performance of the engine is best in the sports mode as in the other two modes the engine lags. The service of the car is also not expensive and tata has a great servicing network in whole country.The best thing is the ground clearance of the vehicle you don't need to worry about the potholes
