Q. Is Duster petrol RXS worth to buy now with that face-lift. is the petrol train is sufficient for city and highway travel?

Why not its adequate. The trim us good .see above answer. But service is an issue with major replacements mainly fuel related like pumps sensors are there in both. but rare till 70000. go for it .

Duster is tough to drive in city with its bulky build. If you are planning to commute more within city go with XUV 300 or same compact SUV they are proven good on highways as well. But yes duster has its own benefits, you will never feels lack of power, whenever you want just force the accelerator and you will get same.
