The Tata Indigo SX was a good car at its time but its engine is not an efficient motor and buying a used one will add on to the cost of repair of its components as the wear and tear is quite high. The car gets a 1405 cc diesel motor, producing 62 BHP and 12.8 kgm of torque only. The new generation of 1.4 L motors are good for nearly double the values of both power and torque, making the car a not so good option for you. It comes with lower mileage figure and the design also seems to be outdated.
