Tata tiago is very fuel efficient car. It gives me average of 25km/ltr in patrol version. While company claim only 23.9 so i am very happy to this aspect.
Another part is its low maintenance.
Next is its overall riding experience is good. Steering is smooth.
Lag is that small parts like plastic materials. Are broken like ac vents nob broke. And door make sound.
Lag is also from service centre. No much responce is given for specific problem such as parts you need for tiago come very late.
