Its always been best to buy a 0 meter car. So if your pocket allows you, always go for it.
If you opt for second hand X, dont go for 2017 model cars as their is a high chance of getting faulty steering rack along with few other manufacturing faults. 2018 is better as their are less number of complains...
Last but not the least, dont see these cars with your thirsty eyes brother....dont wish for materialistic things though i know its really hard to do so because we are bringing up our future generation with such kind of wishes....
