I am using Tata tiago from last 4 months and believe me in this budget this is superior car. I love the feature available in tata tiago. I have Tata tiago revotorq OM, it was around 5.12 lakh and it gives very good and comfortable feeling inside of the car. Led is screen touch, gps available, can connect with aux cable, bluetooth, pen drive, many more features.
Ac of this car is extremely good, even on level 1 of ac, you will feel coolness. If you want to purchase a car within 5 lakhs then own tata tiago, there are many variants available in diesel as well as petrol. Its quite comfortable, last week we drive 700 km in himachal from chandigarh, and it was quite comfortable drive.
