Tiago is a great car from TATA moters .
the key function is ESP function and the HARMAN music system in the car which are found in premium car like audi and BMW .
Tiago is a car which come in budget even if you buy the top model XZ of diesel or petrol version .
the car engine is powerful
petrol have 1100cc and diesel have 1000cc
well I recommend the petrol top version because in that model you will get all features which come in diesel version with the fuel efficiency of 23 k/L.
