I own a Santro 1.1 MT Era 2018 Model. I decided its better to not to go for a higher variant and customize the lower variant as per my requirement, also I had a tight budget. I installed a touch screen system. Also, I installed fog lamps of the Santro magna variant, as of now.I have clocked 20, 000+ kms in Eight months only. The car has ok performance on highway and city as well. On the highway, I have done a maximum of 145km/h Top with minimal breaking and constant speeds. This car has efficiency of approx 24.5kmpl. Which is more than expected. Though Santro is not quick as compared to its rivals such as Swift. It is a very comfortable car and have an excellent amount of leg space of rear and front passenger as well.only the thing that I didn't like about the car is the lack of power in lower gear. I expected more power at lower rpm"s. overall m very happy with it.the other features and safety kit will remain the same apart from transmission 5-speed manual gearbox and AMT unit. Features such as rear parking sensors reverse camera, dual front airbags, and rear wiper/washer, a 7.0-inch touchscreen infotainment system with the latest smartphone connectivity. front and fear speakers will be reserved for the top-end.
