I am using this Tiago xz(Petrol) for more than one year. Minus: Fuel economy, service and NVH Economy is max 11- 12kmpl in city's and 15 to 17 in highway below 70 speed, Not much variation with city and eco mode. After my 3rd service also I am not getting any differences. Mileage is not up to the mark. Vibration and dash board nose is more. AC blower noise is more. Having AMC still dealer charged me rs 600 for 3rd free service
