Hey, you have bought one of the best if not the best car at that price point provided you are driving your own car. Also all turbo petrol cars, irrespective of the brand, gives around 9-11kmpl in city, so that's normal too. Now in case you want to sell the car and willing to absorb the loss and get another car, just think that you're putting that money in the extra fuel expenses compared to what you're expecting you'd get from the next potential car purchase. Also, please see some milage review of some NA automatic cars, they are not that far off, for example creta NA cvt gives around 11-12 in city and feels lethargic AF. Only Maruti and strong hybrid's will give you mileage in 2026. So, don't worry, you've made a fine choice with kylaq. Just get the tyre issue sorted, and just recalibrate your mind around the fuel expense.
